What "religion" does not have a god? Atheism is just a thought held by those who have examined the concept of religions and rejected them just as you have rejected the other many thousands of religions that exist or has existed. If every other one of the thousands of religions that existed is wrong or false EXCEPT yours, then maybe, just maybe, yours is too. Some of us just see the pattern and say if all the other religions that existed were false, then the odds are good that yours is too.
