Being able to measure the current phenomenon, and thinking that it has happened in the past are two separate things. When magma is forced to the surface the ability to "clock it" is reset.
We can measure past movements. Take a look at the Emperor Seamounts (former Hawaiian Islands) stretching all the way to Kamchatka. It took ~80 million years for that chain to form and we dont know how many extinct volcanoes already disappeared under or onto the Eurasian plate. Any variations in the movement of the Pacific plate over that span are small, but there was a significant change in direction about 40 mya.
The dating of the Ocean Floor is based on the layering of magnetic strips, and the Argon Potassium dating method. It would be accurate assuming nothing disruptive has happened. There have only been 4 major disturbances that could have reset/voided any current ability to rule out any assumption errors.
If these disturbances voided the dating of magnetic reversals we'd have evidence for the disruptions in the sequence. Paleomagnetism is what led us to continental drift and plate tectonics, albeit a small school child a century ago could see the evidence for it in an atlas. The Atlantic Ocean has been spreading for over 100 million years at a fairly consistent rate, not even the K-T event wiping out the dinosaurs 65 mya had much effect.
The whole solar system on a whole and the assumption that all the planets and sun were formed at the same time comes from dated rocks and crystals from the moon and earth that give the Solar system a date of 4.3 billion years.
Meteorites provide us with an age of ~4.6 billion years... But I believe most meteorites were once part of larger, planet or Moon sized objects and not remnants of the accretionary phase of the early solar system.
I dont believe the solar system formed at the same time, the planets closer to the center/Sun would appear first followed by the outer gas giants. The one exception to this "rule", if there was one, would be an early planet forming at the snow line because of gases and vapor blown by the solar wind concentrating at that distance - perhaps a planet covered by water, maybe up to 100 or even 500-1000 miles deep.
The snow line is where several myths place the primordial Earth before creation, Tiamat (biblical tehom) formed first and between what would become Mars and Jupiter.
Once Tiamat was carved up, the Earth was given a new orbit where day and night rule (spinning closer to the Sun) and the hammered bracelet called Heaven (firmament - rakia) was left behind at the crossing point.
This is why the firmament was placed amidst the waters, it divided the solar system in two at the snow line. Many creation myths claim Heaven and Earth were one and God separated them...
Even science and the current cosmology are in agreement that the solar system was all formed at the same time. That would contradict your point that the earth came first and that God came along and started transforming it.
Current cosmology doesn't recognize "God" and if the primordial Earth (before creation) was already a planet covered by water (Gen 1:2) then God didn't show up to create for a long time.
And thats what the myths say, they clearly identify a period of time preceding creation when primordial worlds awaited God and the transformation of a planet covered by water into one with dry land and life.
When did life appear? Maybe 3.7-8 bya? How about dry land? Maybe 3.9-4.0 bya? We're still not too clear on when the continents began forming, but if our oldest rock formed in water then plate tectonics came later.
I believe the bombardment of Earth around 4 bya is what triggered the creation of plates, much of the crust was sheared off (some of which plastered the Moon forming its face) and the planet underwent a 3rd episode of differentiation leading to a process of continent building.
My claim is the whole universe was created at the same point in "time" and time had not started yet, as it was not created with time. It was created without form and void. Yet it existed in some form, just not form that had energy, and motion, and by extension, time.
The Earth was without form and void, it wasn't dry land yet, it was submerged. Gen 1:1-2 are not talking about the universe or the Big Bang.
The Bible mentions water, and the Veda's mention water. Science says that is impossible.
The science says the Earth had surface water ~4.4 bya and until we find surface rock that didn't form in water we have no reason to believe the world was not covered by it that far back.
There was only one land mass, and there were no tall mountains, and if there were, they were all destroyed in the event.
There may have been one land mass originally followed by others as plate tectonics fueled the reshaping of Earth's surface, but no tall mountains? Doesn't Genesis tell us the Flood covered the tallest mountains? How does plate tectonics build land masses without building mountains?
God made matter without form (earth) and void (empty space/heaven). "Heaven" has multiple uses.
Heaven is not a void, it is the hammered bracelet, the firmament, and it was created on the 2nd Day. The Earth was without form because the water covered it, on the 3rd Day God revealed it from under the water and called the dry land "Earth" (not this planet, just the dry land). Thats why Earth's "sky" is described on the 4th Day, the Earth was not exposed and named until the 3rd.
Some say that God lives in Heaven.
Is Heaven visible?
The word used in verse one is plural that could mean multiple places that were not designated as the other word ie earth.
The "heavens" became synonymous with Earth's sky and/or the visible objects we see in our sky, but "Heaven" was made to separate the waters and named on the 2nd Day. Therefore Heaven is not the universe, the waters were there first.
The division of gods is needed because humans think that one God cannot do everything, but is limited in ability.
How many Gods create Heaven and Earth in the Euma Elish? One.
Day and night happens because the earth spins. Not just because the Sun shines. The earth started spinning and there was evening and morning.
Day and night happen because the Earth spins near the Sun. If the Earth in Gen 1:2 was spinning further away from the Sun it could be described as being in darkness, especially with the much weaker solar output back then. Of course after the "Light" it was probably spinning differently other than just closer to the Sun.
