1. Lack of any evidence that he exists other than personal inner testimony. The fact that those with inner testimony or faith disagree radically negates the any small weight such testimony might carry.
2. Internal inconsistencies in sacred texts.
3. The fact that humans have been unable to make up a god with better morals than the average man (I mean what the god is said to do, not what he says to do.)
4. Factual refutation of sacred texts.
5. That miracles become rarer and rarer as man understands the world better.
6. The very idea that a creator most wants worship from the created. Do you want your kids to worship you?
7. That the so called god invariably prefers faith to reason. It's the mark of a conman and not a divine one.
8. The fortune cookie like prose of most sacred texts and that humans read even those texts with an obvious meaning like fortune cookies.
But really number one is conclusive.

If there is a god, I want to believe that there is a god. If there is not a god, I want to believe that there is no god.
