Yes, evolution is a scientific theory, but so is relativity. Both are truth and are supported by thousands of valid experiments and observations.

Yes, we belong to the same family as the apes and we share common ancestors with extant apes. It has been proven beyond the slightest doubt by genome projects, amongst other evidence.

No, not all apes would be human by now if evolution were true. Not all whales are blue whales or all birds Ostriches. Why should all apes be human? That arguement makes no sense at all.

So what if Genesis got it wrong? Why are creationists/Intelligent designers so fearful about the first chapter of the Bible being wrong. The authors made up the best story they could. They didn't know as much as we do now. Is it because admitting one thing in the Bible is wrong may make people realise other things are wrong too?
