Want to know more about Atheism..
I'm not technically an atheist, since I figure to be an atheist I'd have to know what real thing the word 'God' was intended to denote, and I don't. Nor does anyone appear to be able to tell me. If God / gods aren't real then they can only be imaginary.
To illustrate with my usual example, what objective test will tell me whether this keyboard I'm typing on is God or not? There isn't one. I can determine whether or not my keyboard is a cup of water, a squirrel, the tune of 'California here I come', light in the green band, a petunia, even a unicorn ─ it's none of those. But no test will tell me whether it's God or not,
And there's also no definition of 'godness', the quality a real god would have and a real superscientist would lack, even if the superscientist could create universes, raise the dead, travel through time, and so on.
So I conclude from what I presently know that the idea of a real God is incoherent and God / gods can only be imaginary.
Since supernatural beings are found in all societies, I suspect we may have evolved to believe in them; it's been suggested that they may play a part in tribal bonding, as does having in common language, customs, stories, and perhaps particularly, explanations of the world and nature. Our brains have evolved to propose answers to questions, to explain what we see or sense, immediately, a very useful survival response, and perhaps that's relevant too, to explain eg grief at death and the consolations of an alternative to death. Death as a place which also punishes can appeal to our anger or our sense of justice too.
Other evidences that God / gods are imaginary are that God never says or does ─ only humans do that. And of course 'the problem of evil', which was noted by the ancient Greeks and has never gone away ─ the existence of evil as the direct refutation of claims that god is aware, benevolent, just and all-powerful.
And finally, the observation that the world behaves exactly as if the only place gods existed was in the imagination of individuals.
