I was delivered to missionary parents in Mysore India in 1951. By the time I was 14 I had realized that no personal god existed, but it took another 40 years to realize that no Faith or set of religious beliefs had 'The Answer'.
I will tell you what this Atheist believes in; What you call "Creation" I call the "Natural Universe". I believe that life and the universe "evolves", which is supported by every single piece of 'observable evidence' that we have available to us.
However, Creation and the implied 'Magical Creator' exist entirely in the gullible minds of human beings, in their imagination. There is absolutely no observable evidence in the Physical Universe or anything on Earth "just poofing (appearing) into existence"; Never has been and there never will be. Creationism is the belief that "Magic is Reality".
I also believe that humans have one life to live, just like any other living creature on this beautiful planet. The belief in a creator and an afterlife cheapens and devalues human life, and encourages people to sacrifice their own flesh and blood in Wars to defend these beliefs.
