Does an Atheist totally exclude the idea of Spirituality?

The only thing that i can say to this is: Even the devil believes in Christ.

It depends on the aitheist. I've read that some believe in a set future of their lives and other don't. I suppose that Atheistism is whatever they want it to be.

Atheism - Literally without theism (religion). If you believe things of that nature then you are not atheist. You by no means have to believe in a major religion to be religious.

Here are the definitions from reference.com: Atheism, as an explicit position, can be either the affirmation of the nonexistence of gods or the rejection of belief in deities. Spirituality, concerns itself with the matters of the spirit, a concept closely tied to a religious belief and faith, a transcendent reality, or one or more deities. If you read both definitions closely, an Atheist does not totally exclude the idea of spirituality. In most cases, spirituality does involve religion but it can just be a "transcendent reality".

To the best of my knowledge an Athiest does not believe in any higher power. I actually dont know what I would consider myself. I believe that there is a higher power be it God, Buddah, Alah or who ever but I dont really follow any major religion either. I have seen to many good things (miracles?) happen to not believe but I think that most major religions get flawed a long the way.
