I'm atheist.
God, as we have grown scientifically, is reduced to playing a smaller and smaller role. We can explain pretty much the entire universe, so the idea of an interceding deity is to me bull****. I don't entirely discount the idea that a god created the universe, but it's unlikely you can prove it either way.
Actually, in a way there almost certainly is a creator - as a civilisation becomes technologically advanced, they will create simulations of things, and eventually they'll simulate a universe. Likely more than once. Within those simulations there may well be further life which creates its own simulations. The chance of us living in the "base" reality is pretty low.
I also endorse the religious views of Dr Gregory House MD - the idea that life is merely a test of devotion is frankly abhorrent. If there is a god, and he bases entry to paradise on blind belief, then that's not a god I care to meet.
All that being said, I don't deny the idea of an afterlife is a nice one. I would love to be reunited with my cats, my grandparents, others I've lost along the way. I just don't think it's realistic. There is however one sort of afterlife I liked especially, I think it's called the Rainbow Bridge. The idea is all the pets are playing in a field, and then one of them pricks its ears, raises its tail and rushes off, because the human it loved has arrived, and they go off together. That's the sort of afterlife I'd like.
But yeah, it's all a load of bollocks meant to ensnare people in a sociopolitical web which keeps a vested elite in power over the purposely blinded masses.
