The Scripture Is False And The Biblical God Is Dead.

[Anomalocaris]

Either way, your argument isn't a compelling defeater of human evolution. 

It's a good argument to be skeptical of the theory of evolution. It's not settled science as atheists claim

To those who are vested in the preconception that evolution is bad thing to believe, any rotten straw, indeed anything they can even pretend to be a straw, they will grasp and assert it to be the life preserver, no, life boat, no, argosy, no, indeed the very ark, that will preserve the light of right creationist faith until the hopeful day they are sure will come when they imagine the flood of evidence for evolution will recede.

And yours is really not even a straw, but merely something you pretend to be a straw.   And that day will very nearly certainly never come.
