"The animals that existed then no more exist today than the basts of today will exist 10,000yrs from now ."
I hate to break it to you but there's plenty of things living today that were around six to ten thousand years ago. Sharks and crocodiles/alligators are just the ones that come immediately to my mind, not to mention most insects.
"there was little water or H2O back then . there was more land than water ."
No. On both counts.
"Geneses explains this and science reinforces it ."
Genesis is wrong about, well, everything and science doesn't support it in any way.
"and as we know fish will travel from salt to fresh easily ."
Sure they will, if they happen to be members of a handful of species capable of the feat. All the rest die rather quickly.
"and most insects can survive under water deep in the earth for a long time ."
Really now? Care to cite an example of an insect species that can survive an entire year buried under the ocean floor?
"frogs have been know to go for up to 5 yrs in drought ."
A drought is not a flood. A drought is, in fact, the complete fucking opposite of a flood.
"as for the ark it was 5 story's tall and each layer held its own ."
Citation, please.
"the animal didn't just roam about freely ."
Even if this were true it doesn't help you in the least. I'm pretty sure your Ark would have been filled to capacity and then some before old Noah was even done with the insect "kinds".
"and they spent a prolong time frozen in time . " and God caused a great stillness . ""
Tell me you don't really believe this shit.
