Is a belief in a higher power, namely God, really a delusion? Is it a delusion to believe that all we see around us, happened for a reason, and was created by an intelligent being? Is it a delusion to believe that we humans have a purpose in life, rather than being the simple chance of biological evolution, with no real purpose in life other than to survive?
In fact if one were to believe that houses and buildings formed on their own, such a person would be called deluded, so how about the universe and life itself?! The reality is that the belief in God is far from a delusion, but something very natural, and something very rational.
The true delusion is a none-belief in God, the Atheist Delusion.
