Mighty large pile of straw you built there
Well if God wiped out every living land animal, then we are all descendent of Noah. Yes, mighty big pile of straw.
Of course we’re all descendants of Noah and his family. Not only is it possible, it is much more likely than evolution. See below:
Science still has not even accounted for the gender problem, among other things! Lol
Couple that with:
DNA damaging mutations being necessary for evolution.
No observed in-species speciation.
The fossil record not supporting evolution.
All mammal orders showing up fully-formed and at once in the fossil record...
and you have the Religion of Evolution.

But that wasn’t the point you made....you are asking to prove creationism by explaining how Noah built the ark and filled it with all the land animals. ..
