Replying to Is God a Delusion?

So last week I picked up two books at the bookstore - "The God Delusion" by Richard Dawkins, and a book which I've lined up to read after about the history of belief and the origins of humanities religions. Taking from what I've read so far, I felt the need to bring my community in on the topics discussed therein.

I have my beliefs and you have yours. But I'd like to hear why you believe in a higher power or why you dont. I'd also like to remind people that the topic of this thread can be sensitive for some individuals, so if you are easily offended, and dont want your ideas scrutinized and questioned by others respectfully and intelligently. Please discuss with care.
