Evolutionary argument for God

If God does not exist, then praying and worship is a waste of time, and therefore an evolutionary disadvantage. However, we observe that most humans are religious. So, logically, God must exist.

Discuss.

IMHO,the evolutionary advantage of dogmatic belief is that it prevents you from going bat-shit crazy without any principles and an illusionary feel of purpose for you and everything around you.

And that belief could be anything-religion,science,magic cupcakes.
After all,you Believe that science explains the world perfectly,and base that on facts and evidence.Others believe that religion explains the world and base that on a book,which produces  a sense of awe in the reader.
