you should check out Kent Hovind also.
your post sounds like you are saying that there were actually land animals (dinosaurs) that survived in the midst of the flood.
If you read the bible carefully you will realize that they would have had to stay treading water for a lot longer than 40 days and nights. Not possible.
Not even considering that God said “Behold, I, even I am bringing the flood of water upon the earth, to destroy all flesh in which is the breath of life, from under heaven; everything that is on the earth shall perish.
The only oxygen breathing land animals that survived the flood were all on the ark!
Dinosaurs were on the Ark. No need to tread water.
