Hey fool, I happen to have a degree in wildlife management, how about you?
So tell me just what your definition of "Kinds" of animals is. Are you trying to tell me that two mammal kinds of animals, say two horses, could then repopulate the caribou, deer, musk ox and every other "hoofed" animal species in the world after the flood.
You really are confused if that is what you believe!
Go back and reread the Bible’s account of Noah. The setting was the known world at that time. The Americas were unknown, as they didn’t have airlines to ferry them back and forth. As a wildlife degree holder, you should know that water, can neither be created nor destroyed. It can change to steam, ice or vapor, or be separated into its component oxygen and hydrogen. As for flooding the world, there is not enough water on this planet to do that.
