Oh, and when we are talking about Deities, the term Agnostic is a misnomer. Gnosticism means "to know" Theism means the implication of a deity. So Theism ad gnosticism measure two completely different things. One (theism or atheism) describes your belief in deities, or in no deities. The other measures the degree of certainty you have of your beliefs. So a very devoted preacher would be a Gnostic Theist. A casual churchgoer who has very loose beliefs might be described as an Agnostic Theist. Someone like me, who is an Atheist, and is quite entrenched in that belief might be calld a Gnostic Atheist. You are sounding like you may be an Agnostic Atheist, which is the one belief that I find the most puzzling, because I find it to be less rational than even a Gnostic Theist.
In my opinion, Agnostic Atheists are essentially conceding that there is virtually no evidence to support the existence of Deities.... however they cling to the notion that deities cant be disproven 100%, and therefore have the same credibility as well established scientific theories. Based on this logic, my 5 year old nephew could scribble something random onto a piece of paper, and it would be just as credible as a team of scientists pouring over empirical data for decades, and then making their best guess based on the evidence.
I think when someone is an atheist, they have to be willing to accept that this universe is a very very complicated thing, and that we humans are quite finite creatures when it comes to our understanding. I think we have to come to the realization that it is OK if we dont ever know the answer to everything. But it sure is fun to try to find out the Truths in the universe without taking the cop-out explanation of "magic" or The Easter Bunny.
