I believe the largest flaw with Intelligent design is that it contradicts itself.

I could be wrong but I believe that intelligent design works on the idea that as beings we are too complex to have simply evolved and come into existance as we are today. This being said, if you believe this to be the case, I pose a question for you. Where did our creator (who has to be infinitely more powerful and complex than we are to design something as intricate as us) come from? He simply can't have come into existance because your arguement states that we couldn't have simply come into existance...so where'd he come from?
