This is not something I 'believe' this is fact, as far as I am concerned. I don't feel I have to prove my assertion. I don't have angst or struggle about this.
I don't have to 'prove' that a God doesn't exist anymore than I have to prove that fairies, Santa Claus, the Easter Bunny, an unicorns exist.
And I tell people, when they start in on me, that I have already read the bible and it didn't impress me as emperical evidence. Nor do anecdotal stories. I am not sure there really was a man named Jesus really. Maybe his acts were made up.
The nice thing about knowing that there isn't a diety is you can stop worrying about the afterlife and start doing the best you can to make the life you are living wonderful and meaningful for you. Sounds selfish. Christians have always told me that the 'self' is what you have to stop thinking about and give yourself to do God's will.
Don't have to do a unicorn's will or a do a fairies will or do God's will. All of that is equally absurd.
I am not an intellectual or a great thinker as you can mostly see here. I cannot cite nor repeat the great arguments about the great thinkers and scientists of the world. But within my own limited sphere, I embrace the darkness of the void when I die and I enjoy the human connections in my life now.
I don't understand what could be more comforting than the thought that everything is here, right now, for good or ill.
So no, there isn't a god and I don't have to prove it. And I don't want to hear the illogical and totally absurd and delusional 'evidence' anyone may have.
