Here is my basic reasoning on why I reject ID:
1. People who support ID say they do because of how complex life and the universe are. They say such complexity certainly must have been created by a higher being.
2. I reject this because one is left wondering: Who created the creator?
3. If the universe is so complex that it needs to have been created, then why does the creator not need to be created. The creator is, after all, more complex than the universe itself.
4. I say leave out the extra step of the more complex creator and just leave the less complex universe by itself.
