It's not that I don't believe in a higher power, it's just... I really don't care if there is one or not. :/ That and I personally feel that if there is a higher power, they really don't care or pay enough attention to humans anyway, so I doubt he/she/it would notice if people were praying to him/her/it. *shrug*
I couldn't help but feel I detected agnosticism in your post. Agnosticism isn't really so much a religion so much as it is a stance on religion.
Basically, it means you believe you can't know for sure whether there's a god or not, that it's not possible to prove or disprove, whereas Atheism is the firm belief no such thing exists. (In theory, you could be both Agnostic and <religion of choice here>.)
