It was God, and no- ID studies the created design of man and species- not hte evolution of man, but it makes no claim as to the creator- just that the desing seen in nature and biology is intelligently designed per the mass amounts of design complexities that defy natural laws which render small accumulations of biological mistakes impossible
I reject the underlying assumption because:
1. Current life forms are far from perfect.
2. Life forms are evolving daily both due to the hand of man and natural selection (Think MRSA).
Of course once you have a point of view, your built in filter makes sure only supporting data gets through. That is why Muslims stay Muslims, Liberals stay liberal and so on. We humans aren't particularly rational no matter what our IQ. Me either when it comes to the stock market:-)
