Clarence you cheeky monkey, trial and error.

I am atheist because nobody has produced any falsifiable evidence to support the existence claim of any god in the last 5,000 years. Moreover, it is trivial to show that both the god of the Bible and the god of the Torah cannot exist.

I’m an atheist because I don’t have a reason to believe which is a damn good reason to not believe something.
You sound like an agnostic because you imagine yourself to be clever. If you were clever you would know as I do that the religious are people too and all people are equally clever but if you get smart enough to know how much you don’t know you’ll be shamed out of such conceits.

It might be a metaphor for all the inescapable realities of life. Doesn’t much matter what we call it - it’s still there.

Interesting choice of literary/societal character with devil. Why a devil?
