shady, this is all humans who've lived at any point in time ever. not just currently living
and as for noahs ark, it said he took "two of every KIND of beast" not nessicarily 2 of every species, it is quite possible he took two random dogs, large cats- etc which then, thru verity in a system, became the various breeds we know today. further more if he took two dinosaur eggs, 2 of some particular bird egg- etc etc, more space in food and suchlike would be saved, and yet further, does it say he even had to feed them? remember, you assume that God must follow his own laws- God does not allways doso, it is entirely feasable that God simply said to the animals to stop eating, stop bickering, and get in the ark before he opened the door and killed them all. and insodoing gave there bodies, in some way or another, in this ensample, supernaturally- nurishment enough tolive
as for the amount of water, remember, it said "and he let loose waters from above and below the earth (paraphrase)" which implys that not all water was rain,
assume god allowed the Icecaps (assuming there were some then) to melt, this floods a great deal of land. Noting that this land is probobly a pangeiac continent (not 7 continents, but 1 supercontinent) much of it would be covered in water, at this point, fissures in the ground might have opened and help supply water, also, it is believed that there was a great sphere of water outside the earth, prior to the flood, which gave the earth its edenlike qualitys...
as for how did the ants and such get to there various homes, simply put, Pangea, Since all the continents were one, the Ants and Kangaroos simply walked/hopped there way somewhere, and while living there, the continents shifted.
I didnt read the whole noahs ark thing, but those are relitivly sound refutes for what i did read.
Heaven hotter than hell? cool, least i wont be cold up there
Hoorah.
