That is an illogical assertion. The existence of God is orthogonal to the validity of evolution as a mechanism for speciation. The existence of God doesn't require that He is the cause of speciation nor does the non-existence of God prove that evolution is valid. As I've mentioned in the past, there are other lesser known theories for speciation that don't assert evolution but which are still stronger theories in any scientific sense than creationism in its various guises. The God versus evolution dichotomy is a false one, a strawman that is apparently stimulating to some people but nonetheless worthless as an argument.
You are evading my point. If God exists, why would He lie about creating man? Why could he not have created the different species? The main argument of evolution is that there is no other way that species could have come about. If evolution admits that God exists that argument is null and void. So yes, evolution requires that there be no God. That evolutionists do not admit it is because they know quite well that there is no way that abiogenesis could be true, so they are willing to have half a loaf rather than losing the whole argument.
