Here is the relevant Enuma Elish part. It is the very beginning. Now, you say that the two waters were from the solar wind and the asteroid belt and a remembered tale from space aliens. IIRC Sitchin said that all the earth's waters came from the Asteroid belt as did the earth itself. There is no planetary cosmology in this story.
1 When the heavens above did not exist,
2 And earth beneath had not come into being —
3 There was Apsû, the first in order, their begetter,
4 And demiurge Tia-mat, who gave birth to them all;
5 They had mingled their waters together
6 Before meadow-land had coalesced and reed-bed was to he found —
7 When not one of the gods had been formed
8 Or had come into being, when no destinies had been decreed,
9 The gods were created within them:
10 Lah(mu and Lah(amu were formed and came into being.
11 While they grew and increased in stature
12 Anšar and Kišar, who excelled them, were created.
13 They prolonged their days, they multiplied their years.
14
Anu, their son, could rival his fathers.
15 Anu, the son, equalled Anšar,
16 And Anu begat Nudimmud, his own equal.
17 Nudimmud was the champion among his fathers:
18 Profoundly discerning, wise, of robust strength;
19 Very much stronger than his father's begetter, Anšar
20 He had no rival among the gods, his brothers.
In 20 lines we have the original solar system. Now line 4 has another translation that refers to Mummu-Tiamat, Mummu is Apsu's companion:
"He appeared in the Babylonian creation myth, the
Enuma Elish, as the
vizier of the primeval gods
Apsû, the fresh water, and
Tiamat, the salt water.
[2] and sometimes referred to as their son."
Yet he's not mentioned in the opening 20 lines but appears a few lines later as already existing. That might be why line 4 includes Mummu in at least 1 translation, its a minor point but still noteworthy. No (other) gods had formed yet, no 'destinies' decreed. Its talking about planets and their orbits. The Apsu's fresh water and Tiamat's salt water mingled and a pair of gods were born between them, the male and female siblings Lahmu and Lahamu - Mars and Venus.
Okay, the Enuma Elish has just described the 4 inner planets and sun, but it places Tiamat on the other side of Mars... Venus and Mars were born between Apsu and Tiamat. Remember the 9 Mile Canyon rock art with the horned deity with 3 sheep to it's left and 5 to it's right as the warrior with bow and arrow approaches from the right and below?
While Mars and Venus were still growing another pair of planets began forming, Ansar and Kisar (Saturn and Jupiter, Sitchin translates them as foremost of Heaven and foremost of firm worlds). They give birth to Anu (Uranus) who in turn begat Nudimmud/Ea/Enki (Neptune). There we have the 4 outer gas giants.
21 The divine brothers came together,
22 Their clamour got loud, throwing Tia-mat into a turmoil.
23 They jarred the nerves of Tia-mat,
24 And by their dancing they spread alarm in Anduruna.
25 Apsû did not diminish their clamour,
26 And Tia-mat was silent when confronted with them.
27 Their conduct was displeasing to her,
28 Yet though their behaviour was not good, she wished to spare them.
29 Thereupon Apsû, the begetter of the great gods,
30 Called Mummu, his vizier, and addressed him,
31 "Vizier Mummu, who gratifies my pleasure,
32 Come, let us go to Tia-mat!"
The planets had erratic orbits, Apsu and Mummu tell Tiamat they must be dealt with...
59 Ea, who excels in knowledge, the skilled and learned,
60 Ea, who knows everything, perceived their tricks.
61 He fashioned it and made it to be all-embracing,
62 He executed it skilfully as supreme—his pure incantation.
63 He recited it and set it on the waters,
64 He poured sleep upon him as he was slumbering deeply.
65 He put Apsû to slumber as he poured out sleep,
66 And Mummu, the counsellor, was breathless with agitation.
67 He split (Apsû's) sinews, ripped off his crown,
68 Carried away his aura and put it on himself.
69 He bound Apsû and killed him;
70 Mummu he confined and handled roughly.
71 He set his dwelling upon Apsû,
72 And laid hold on Mummu, keeping the nose-rope in his hand.
73 After Ea had bound and slain his enemies,
74 Had achieved victory over his foes,
75 He rested quietly in his chamber,
76 He called it Apsû, whose shrines he appointed.
Ea (Nudimmud) poured slumber on Apsu robbing him of his creative powers
79 In the chamber of the destinies, the room of the archetypes,
80 The wisest of the wise, the sage of the gods, Be-l was conceived.
81 In Apsû was Marduk born,
82 In pure Apsû was Marduk born.
83 Ea his father begat him,
84 Damkina his mother bore him.
85 He sucked the breasts of goddesses,
86 A nurse reared him and filled him with terror.
87 His figure was well developed, the glance of his eyes was dazzling,
88 His growth was manly, he was mighty from the beginning.
89 Anu, his father's begetter, saw him,
90 He exulted and smiled; his heart filled with joy.
91 Anu rendered him perfect: his divinity was remarkable,
92 And he became very lofty, excelling them in his attributes.
93 His members were incomprehensibly wonderful,
94 Incapable of being grasped with the mind, hard even to look on.
95 Four were his eyes, four his ears,
96 Flame shot forth as he moved his lips.
97 His four ears grew large,
93 And his eyes likewise took in everything.
99 His figure was lofty and superior in comparison with the gods,
100 His limbs were surpassing, his nature was superior.
101 '
Mari-utu, Mari-utu,
102 The Son, the Sun-god, the Sun-god of the gods.'
103 He was clothed with the aura of the Ten Gods, so exalted was his strength,
104 The Fifty Dreads were loaded upon him.
105 Anu formed and gave birth to the four winds
106 He delivered them to him, "My son, let them whirl!"
107 He formed dust and set a hurricane to drive it,
The text describes Marduk and says Anu (Uranus) provided him with 4 winds (moons), but it says Marduk was clothed with the halo of Ten Gods. Apsu, Mummu, Lahamu, Lahmu, Tiamat, Kisar, Ansar, Anu, Nudimmud and Marduk. He was brought forth by Neptune, next Uranus supplies 4 satellites - and if you think thats impossible, something major happened to Uranus - and the remaining text on tablet 1 describes the armies being formed for battle with Qingu becoming the leader of Tiamat's forces.
The non space alien version is less dramatic: fresh water from the rivers and salt water from the ocean mingled in the tidal estuary where people lived.
1 When the heavens above did not exist,
2 And earth beneath had not come into being —
3 There was Apsû, the first in order, their begetter,
4 And demiurge Tia-mat, who gave birth to them all;
5 They had mingled their waters together
6 Before meadow-land had coalesced and reed-bed was to he found —
7 When not one of the gods had been formed
8 Or had come into being, when no destinies had been decreed
These events were before the Earth just as Genesis describes a dark, water covered primordial world before God's 'light'.
Please point out to me where the creation story says anything about the sun or planets? In fact, according to the story above, there were no planets or anything when the "waters mingled". Apsu is the god of fresh water and not the sun.
Tab 4
93 Tia-mat and Marduk, the sage of the gods, came together,
94 Joining in strife, drawing near to battle.
95 Be-l spread out his net and enmeshed her;
96 He let loose the Evil Wind, the rear guard, in her face.
97 Tia-mat opened her mouth to swallow it,
98 She let the Evil Wind in so that she could not close her lips.
99 The fierce winds weighed down her belly,
100 Her inwards were distended and she opened her mouth wide.
101 He let fly an arrow and pierced her belly,
102 He tore open her entrails and slit her inwards,
103 He bound her and extinguished her life,
104 He threw down her corpse and stood on it.
105 After he had killed Tia-mat, the leader,
106 Her assembly dispersed, her host scattered.
107 Her divine aides, who went beside her,
108 In trembling and fear beat a retreat.
109 . . . . to save their lives,
110 But they were completely surrounded, unable to escape.
111 He bound them and broke their weapons,
112 And they lay enmeshed, sitting in a snare,
113 Hiding in corners, filled with grief,
114 Bearing his punishment, held in a prison.
115 The eleven creatures who were laden with fearfulness,
116 The throng of devils who went as grooms at her right hand,
117 He put ropes upon them and bound their arms,
118 Together with their
warfare he trampled them beneath him.
Thats where the comets etc come from, when world's collide stuff goes flying. I'd expect this invading planet to be corralling all sorts of debris. But whats all the fuss? Marduk murdered a woman and it ended up as the basis for the Enuma Elish and Genesis? No, Tiamat is female because Marduk is male and their collision(s) produced life.
135 Be-l rested, surveying the corpse,
136 In order to divide the lump by a clever scheme.
137 He split her into two like a dried fish:
138 One half of her he set up and stretched out as the heavens.
Tab 5
62 [(Thus) the half of her] he stretched out and made it firm as the earth.
63 [After] he had finished his work inside Tia-mat,
64 [He spread] his net and let it right out.
65 He surveyed the heavens and the earth .
Thats the first mention of Earth... Half of Tiamat was stretched out to form the heavens, firm, ie biblical 'firmament'.
Tab 5
1 He fashioned heavenly stations for the great gods,
2 And set up constellations, the patterns of the stars.
3 He appointed the year, marked off divisions,
4 And set up three stars each for the twelve months.
5 After he had organized the year,
6 He established the heavenly station of Ne-beru to fix the stars' intervals.
The great gods are the planets, the mystery is Nibiru/Ne-beru. The name of Peru comes from Biru and Votan/Wotan is a Mayan (and Norse) god.
12 He created Nannar, entrusting to him the night.
13 He appointed him as the jewel of the night to fix the days,
14 And month by month without ceasing he elevated him with a crown,
15 (Saying,) "Shine over the land at the beginning of the month,
16 Resplendent with horns to fix six days.
17 On the seventh day the crown will be half size,
18 On the fifteenth day, halfway through each month, stand in opposition.
So there's the Moon finally
73 [Now] the eleven creatures to which Tia-mat had given birth and . . . ,
74 He broke their weapons and bound them (the creatures) to his feet.
75 He made images of them and stationed them at the [Gate] of the Apsû,
76 To be a sign never to be forgotten.
Now thats interesting, if the Apsu had become Neptune because Ea robbed the sun of its power to create more planets, then these creatures at the Gate of the Apsu might refer to Kuiper Belt objects. Marduk bound them to his feet, researchers are looking at them to find the 9th planet.
Tab 7
16 Who established, the pure heavens for the gods,
17 Who took charge of their courses, who appointed [their stations]
Indeed... Marduk has changed the solar system. Something has dragged the planets away from the sun's equatorial plane.
https://en.wikipedia.org/wiki/Orbital_inclination
Jupiter's over 6 degrees off kilter
83 Who created the earth on the water and made firm the height of heaven.
124 As (49) Ne-beru let him hold the crossing place of heaven and underworld,
125 They should not cross above or below, but should wait for him.
126 Ne-beru is his star, which he caused to shine in the sky,
127 Let him take his stand on the heavenly staircase that they may look at him.
128 Yes, he who constantly crosses the Sea without resting,
129 Let his name be Ne-beru, who grasps her middle,
130 Let him fix the paths of the stars of heaven,
131 Let him shepherd all the gods like sheep,
132 Let him bind Tia-mat and put her life in mortal danger,
133 To generations yet unborn, to distant future days,
134 May he continue unchecked, may he persist into eternity.
135 Since he created the heavens and fashioned the earth
The sign of the cross has great antiquity... But if the Earth (and the firm, stretched out Heaven) came from Tiamat, then Tiamat was a planet.
And the lord stood upon Tiamat's hinder parts,
And with his merciless club he smashed her skull.
He cut through the channels of her blood,
And he made the North wind bear it away into secret places.
and so the Earth was carried away to a new location
