Belief and empirical fact are not mutually exclusive.
The question is does empirical evidence prove a thinking intelligent creator or a natural
non intelligent natural process ?
I'm sorry it seems very easy to me that intelligence had something to do with our universe and life as we know it.

The cite above is a good example of why I don't believe in intelligent design. If there are 64 possible codons and 20 amino acids, why do some AAs have 6 codons and some only one. Seems to me that an intelligently designed sysytem would have three for each AA and 2 each for stop and start.
