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.
