Argument #1: Transitional Fossils

[Esquilax]

I believe creationists do believe and accept that there are indeed changes and transitions that take place within organisms. But would not evolution have to show that at some point there was an original organism from with all organisms would of eventually evolve from?

Nope; since evolution demonstrably happens, and genetic research shows plenty of commonalities, it's a pretty easy inference to then say that common ancestry is supported.

But evolution would still be happening, even if you were to prove common ancestry to be dead wrong.
