I wouldn't call myself an atheist, and certainly not an "agnostic"
, though I am dead certain there is no higher power. Why am I so certain of this? Because there's no reason to postulate a god in the first place, outside of human emotion and drive to feel a sense of understanding and control, even if it's fabricated in your own head. Now, I can understand that drive, understand that that is intrinsically tied to what makes humanity what it is. Religion is natural, a matter of fitting the vast unknown into a limited schema. Hell, I'd assume anything capable of even the slightest degree of abstract thought possesses something we could call religion, even if it's not as complicated as what we manage to put together.
Really, the drive extends to philosophy, and even science. Philosophy is, of course, the same self-originating attempt at explanation religion is. Hell, the distinction between the two is rather thin, and changes depending on who you ask.
Science? Science is that drive constrained, subject to rigor and externalized standards and scrutiny. Hell, the average layman has to take it on faith that scientists, that doctors, know what they're doing. And that faith is reaffirmed by the fact that the process works, and has very noticeable impacts on their lives as a result. Prayer has never stopped a plague, medical technology has. Prayer has never provided food for the starving (well, I don't know, I'm sure there were cases of "pray to our god or we don't let you have any food" conducted by missionaries...), agricultural technology
does.
Of course, we could go further: no unnatural consciousness has created or guided life, yet man has (synthetic bacteria (still an ongoing effort as far as I know, but still progressing...) and genetic engineering), from knowledge of how life works (admittedly still rather incomplete, but that knowledge base is ever growing). No spirit has animated the inanimate, given awareness or speech to unliving objects, yet mankind has, albeit to a limited extent. Really now, what does Man appear with all that in mind? Knowledge is our apotheosis, and it should be clear why I wouldn't call myself an atheist.
