Looking at the sheer immensity of the universe
The universe is so huge that if there is a god the planet earth and its inhabitants cannot be his greatest creation.
Looking further through the eyes of science I see no need for a god for creation including the creation of life to happen. Some people point to the complexity of DNA as evidence for intelligent creation but all I see is evidence of trial and error via evolution over a period of billions of years.
I see no reason to worship some sort of vague man in the sky person that no one can see.
There is no afterlife. No heaven, no h*** nothing beyond this life.
Prayer and a false hope in a better life after this one is a waste of time.
Rejoice in this the only life you can ever have. Many things could have happened to prevent you from ever existing.
