Let me start by making it clear that I am an atheist.
The problem I have with the atheist agenda is that is stops at 'the non existence of God' - the same logic is not applied consistently to the whole of the human condition.
If I examine my life and use this same 'spaghetti monster' logic, I am drawn to the same conclusions about all my actions and activities - they are all as equally pointless and irrational as worshiping God.
If I rationally examine my sense of self I realize that it is just a genetic innovation - it encourages self preservation - genetic selfishness creates a genetically induced illusion of self worth.
My desire to survive is itself as delusional as a belief in God - pain and my fear of pain are a genetically induced survival mechanism I am in thrall to.
If I believe in God and survive then it is no different to not believing in God and surviving - nature will select for survival.
But my actual survival is meaningless whether I believe in God or otherwise.
This is the only conclusion that can be logically formed from a real examination of life.
Atheism is merely another tribal display - a peacock's tail trying to attract a mate through a verbal display of intelligence.
Sorry, I didn't read the thread.
But yes, our lives are totally pointless and meaningless. So what? Just follow your instincts and try to have as much pleasure as possible. That's it, really.
An old wise man once asked a young boy: "Do you know why are we all living on this planet?"
"We are just hanging around to waste our time, you know" — answered the boy, without stopping to play with his smartphone.
