You are knocking on a deaf man's door if you seriously expect a direct answer to your question from creationists.
I have posted a question over and over and none have answered it as of yet ("What happened to the aquatic reptiles like the Pleisiosaurs. Surely they did not drown in the deluge?". YECS insist that Dinosaurs lived side by side with people and they all died in the flood and yet this includes the aquatic species too. Imagine drowning in the very water that is your natural habitat
And it's all so unnecessary. The first few chapters of Genesis are brilliantly clever: and none of us modern English speaking types get it. There are layers upon layers of meaning, weaving the number 7 into all manner of textures in the very language used. EG: In the original Hebrew, the first sentence starts of with 7 words, the second sentence with 14 words, and there are various repeated phrases like "And god said" in multiples of 7 as well.
In a world without TV, but instead with a rich oral tradition, this would have grabbed the attention of the ancient world as much as a well designed movie intro. To ancient ears it's almost as recognisable a motif as the Star Wars or Superman theme. For the Babylonians had the Enuma Elish creation myth, which read a bit like their national anthem and was read out once a year. It was written on 7 tablets and moved over a creation sequence of about 7 stages. Genesis would have tuned them in to the special nature of the writing. It is NOT a literal history, as if an observer were standing by watching what God had done. It's a carefully crafted document as to WHY we are here, not how we got here. And it is a theological bombshell exploding the Babylonian myth. It reacts to and critiques it. It's a poem: a cultural counter-narrative, and it says many 'heretical' things to the ancient world. Like stars are OUR servants, operating like calendars telling us the seaons, and not some gods to sacrifice babies to. The world was made by the loving care of ONE god, not by many gods in civil war. Etc, etc, etc.
It's carefully crafted in a poetic form. Just a few more details illustrate this. The first 3 days show the forms, the second 3 days the filling of those forms. Just pan down to the table here. Basically, Day 1 = Let there be light: Day 4 = let there be sources of light, the sun, the moon, the stars.
Day 2 = separation of the waters (a BIG theme in Babylonian literature where the goddess of chaos is cut in half and her body becomes the land and sea) but God just SAYS they are to separate: there are no battles between the gods in the making of this world. Day 5 then fills the air and water with birds and fish.

ETC. It's a carefully crafted poem that anyone who has eyes to read and comprehension to understand can see. But Young Earth Creationists just refuse. They can't see. The sad irony is that their
reaction to evolution is so strong, they are letting Charles Darwin dictate how to read the passage
anyway. They read it in direct antithesis to Darwinianism, and completely miss the rich cultural analysis and theology that is there. It's just sad, and
not a little moronic.
