This is something that I have often pondered in the past and now science is finding it to be more true than the alternative. You can read about it here:

Basically it has to do with the supernatural being literally "all in the mind," i.e. supernatural phenomena being caused directly by some sort of stimulation of the brain. You can also read more about this subject in Carl Sagans book "The Demon Haunted World." I have often questioned the reasons or realities of life, but in the last couple of years I have begun questioning it with scientific questions and searching for the truth behind reality by what can be shown and proved through logic and reasoning. I have just not found enough evidence for a god to believe. Do I think the universe is more than just us? Oh yes, I am sure our universe is a part of some ever grander structure. But that in itself is also reason to feel lucky to be alive and to cherish every moment that we have as special, to see every life as something that should not be wasted. In this random universe, our few moments of awareness are brought about in a total random fashion, and our lives filled with and directed by random cause and effect - from the process of evolution to the humand, to the combination of my DNA making up who I am , to even our chance meeting and you reading this sentence. All created and shaped by random cause and effect. Visally this is represented by a fractal, exemplified by the random growth of trees, the beaches of rivers, and the shape of coast lines around the world. Since I have been looking for the truth in visible, replicatible evidence, I have found the mystical and supernatural slowly seeping away, but I am okay with that. I want to know the truth more than I want to be comforted, and will accept as truth what evidence I am shown. I feel lucky that I am even able to be alive and aware, let alone questioning my existence and the universe around me. I stopped searching for the answers to these questions in my "heart" and started searching for the "truth." Don't get me wrong, I still think some questions should be answered with the heart - mainly questions OF the heart! Anyhow, I am very satisfied with the answers science has so far given me - I find it very awe inspiring and magnificent - and I have answers with evidence, that truly make logical sense. Which is exactly what I was looking for.
