"Evolution is changes that occur over millions of years to a species...which, to a point, I agree with. If it ends there, yeah, I'll buy it. I don't buy that a new species can be formed by this."
How about several decades - or even several years? Consider these:
The bacteria that eats Nylon. A man-made substance that didn't exist before the 20th Century.
MRSA. Need I say more?
Besides, if Creaion is fact, then the Common Cold would have become extinct, as the early humans became immune to the original strain.
PROTIP: Microevolution is still Evolution. Even bacteria/viruses changing to adapt to their new environment (to survive antibiotics/vaccines) still contradicts Biblical Creation.
Here endeth the lesson.
