My answer to the weasel Intelligent Design types, is, "If I am the product of intelligent design, a) why do men have nipples and (c) why did God tell the Jews the foreskin had been a terrible cockup"
As for the argument about using the God idea to fill in where we don't yet have answers, well, that's the old God of the Gaps argument. Unfortunately, the gaps have been getting fewer and farther apart as science has been able to explain more and more.
My own theory is that darkness moved on the face of the void and all was nothingness and God saw that there was nowhere to ride a bike, so god said, "Let there be light and there was light", and you could see for miles, but still there was nowhere to ride a bike. So created he the world but had to wait for millions of years until a species evolved that was intelligent enough to invent the bicycle. Unfortunately, they also went on to invent the motor vehicle, so God has created Global Warming to wipe us out and start again.
