Time and again I guess every individual with an iota of intelligence must question their belief system, more particularly the belief in an Omnipotent, Omniscient and all pervading force. Atheists are generally regarded as an immoral lot which is far from the truth, they merely question the need for a supreme being where none is needed.
I find it extremely disturbing that an entity that has not been seen, or properly described for thousands of years still is regarded as a possibility. Most people would cite some miracle to prove me wrong but they fail to understand the probabilistic and impersonal environment we live in. Given the myriad of phenomena that can influence an outcome in our everyday life, it is in fact no miracle that something out of the ordinary will happen eventually. However, it also means that most of the time it will not. We just tend to remember the "happy" coincidences and ignore the rest thus further perpetuating this belief in miracles.
In fact, the abode of the almighty is getting smaller and smaller everyday. Ancient societies saw the God in the sky and in the trees and animals that roamed about, they saw God in the stars and in the planets. Now that we know what these are, God has been pushed back to the realms of parapsychology and mysticism and as medical science makes progress God is being displaced here as well.We now know how the Universe began but we are still in the dark about the initial moment of the Bang which means that as far as I am concerned God existed in an infinitesimal space when the Universe was younger than the Planck time.
God is just an euphemism for ignorance, all that we do not understand can broadly be classified as "Godly" and this is very unlike what we are taught to believe. Besides, here is my rationalization for not believing:
Lets assume that God exists then by definition this entity has to be the smartest and most powerful thing that ever existed. Assuming that this entity is responsible for this world around us and for all the minute details, I think he/she would be extremely interested in having a conversation with someone who actually understands the complexity and appreciates it rather than a devout believer who has spent his life just on the belief that everything is sustained by God and has no knowledge about the inner workings of anything. Thus, it would serve us well to be non-believers and try and understand the world as is without involving God in between. This would ensure that we gain an understanding of the world we live in and also that we can carry on a detailed conversation with God on the validity of using Cyclic Bessel functions of the 12Th order in modeling ground wave propagation when the time comes. If he doesn't exist then, well, we still gather the knowledge. Also, this methodology has practically no downside, God is not known to be vengeful so you can deny his/her existence without fear of retribution. Even if you are wrong, God forgives everyone so we are all set.
Logic dictates belief. It takes a lot of courage and self discipline to ask yourself the hard questions. There are no right and wrong answers, just answers.
