I'm one who believes the facts that are put before me, and even after being raised in a very Hindu household I have been pushed in the direction of not believing in god, or any other sort of divine power. For all I know, there could be one, but I'm just not aware of it, and in turn do not believe in its existence.
I don't think badly or anything of people that do believe though. If you do, I don't feel its right to think differently of or force my views on them either. So I don't
How I see it, it seems like people needed something to use as an explanation for the things they didn't fully understand, and also felt the need for there to be some sort of higher power, whether that be a single deity, many, or belief in some sort of power or system. Which I find understandable.
I probably left some stuff out, but that's probably enough to get my view across.
