If the genetics of living organisms were wildly different, no doubt that would be used as evidence against creation/ID also, with the reaoning that *If the designer were so intelligent, why would he make things so different? It's not efficient. It doesn't make sense.*
Heads I win, tails you lose.
It pretty much does. The word 'ape' is just a sign or a symbol. It has whatever meaning we assign it. Right now, the scientific consensus is that the word 'ape' means 'the hominoids,' which includes humans. It has nothing to do with gods, morality, or metaphysics -- it's just a word used to describe several species.
If you want, you can dismiss that definition as scientific jargon unsuitable for vulgar conversation. But I think it is very suitable for this thread.
