My understanding is that creationists' problem is not whether we evolved from monkey or not, but rather that we evolved from something
That's what they are so much emotionally opposed to evolution, and as a result they reject the obvious fact that evolution is real and we are part of it
From that point of view it doesn't really matter whether man evolved from monkeys or apes, or they just share a common ancestor, it's the very fact that man evolved that some ignorant people find unacceptable
