I should add that your whole argument assumes apes evolved to humans. Another circular element. It’s “since we know apes evolved to humans over millions of years, therefore something that evolved in much shorter time should have less of a DNA difference”. Then you ALSO assume that the elephants have a large DNA difference, even though we don’t have the DNA.
One need not assume ape to human evolution to note that there is only a 2% genetic DNA difference between humans and chimps.
Why is it acceptable to you that an animal fresh off the Ark can, over a few thousand years, become many different species all over the Earth accumulating DNA differences far in excess of a 2% difference, but absolutely unacceptable that a slow incremental change over six million years could accumulate a similar 2% genetic DNA difference between humans and chimps?
Would you agree that camels are all one “kind”?
There was then, just one pair of camels on the Ark?
