People need a God in order to rationalise why their lives are such a mess and why they should do nothing about it. Has worked like a charm for 5000 years. I do believe in God but I believe humanity are just an experiment that he did just to make him chuckle. He is not at all bothered by our gross stupidity and cruelty to one another.
I also believe in aliens. Not believing in other intelligent beings is like an ant in a colony who doesnt believe in humans.
