Ones surroundings give you certain knowledge of the existence of a Deity.

I thank Zetsubou for the Debate Challenge and the chance to explain myself. I am slightly confused of why the burden of proof is laid upon me since usually the one stating "there is" something or another has to prove it. For example, if I were to say that faeries existed in gardens, I would have to prove there are faeries. Not the person who says there is not. But, regardless of my confusion, I will still post my argument out of respect to Zetsubou. I am an atheist and a strong believer of natural selection, evolution and the Big Bang theory. Although my family always pushed that the Bible was a legitimate reason for my existence I never agreed. Here's why; a) the implausibility of there being a God who watches my every move, listens to my every thought, judges my life and can/will send my soul to a place of eternal suffering or bliss, b) science can explain the world's existence along with my own with facts and figures instead of just one book and a horde of "believers" c) the sheer number of religions before and after Jesus's appearance. Reason A started my doubt since the basic idea of a God seemed unnatural and superstitious. I couldn't fathom why a God would exist let alone why it would even be concerned with my life. Reason B presented an alternate explanation for existence which had been proven beyond a single doubt in my mind. It was easy and logical to understand at a young age and then comforting and reasonable as I grew older. The idea that our universe was created by the Big Bang was accessible and well explained by leading cosmologists over the years. Hubble's Law, Expansion of Space, Cosmic Background Radiation experiments (WMAP), Primordial elements, Galactic evolution and expansion and also Radiometric dating were used to help prove such a complex theory. And all reservations for such a theory based upon problems have been studied through experiments which are still underway even today. Natural Selection has been proven through evolution of species shown in fossils and skeletal structures from millenniums ago. Science has been explaining mysteries for thousands of years and each day we grow closer to more discoveries. But in regards to religion, I never saw science and religion as being homogeneous. Science is about pushing boundaries and challenging the unknown with skill and knowledge. But religion was about accepting what we don't know and living with the mysteries as God's work. It seemed like a cop-out to me. As though the scientists went, "I don't know what this is or why it acts this way so God must have done it." What was considered God's work thousands or even hundreds of years ago have been explained by theories now. Why should our existence be any different? If they thought disease came from sin back then, how can they be trusted for explaining our origin? Lastly, Reason C definitely showed fallacy in the idea of any religion. How can you accept one religion as truth when there have been hundreds of ones before it and then after it? Societies will condemn religions like Scientology as foolishness. But those who believe in it have just as strong conviction as Christianity, Judaism or Islam. Also, what about the Roman or Greek Gods? They were pushed aside by monotheistic religions but for thousands of years these ideals were law and reality for these people. In all societies, especially ones not corrupted by modernization or westernization, you will almost certainly find a religion, one that will stretch back through generations. They might believe in multiple spirits, sacrifice, possession by demons, etc. And when they are found, the majority of the world will laugh at the implausibility of their beliefs and stories. But why are the Abrahamic religions so easy to accept? Aren't they just as puzzling as the ancient religions? When I look around and see other people, trees and buildings, I do not see a God's work. I see biology and architectural work by man. I see the products of evolution. I experience scientific phenomena like gravity everyday. Our hydrogen balls dubbed stars are not made by a God. Our oceans filled with life are not made by a God. My life was not given by a God. I look towards science for the reasons why and there I find the truth and logic. Since hundreds of religions have different explanations for the origins of different species of life, how do you pick one as truth? Like I have explained before, based upon the implausibility of a religion and then the discrepancy of religion itself, along with the available scientific explanations, I will see biology. Not a spirit, or a gift of God. So Zetsubou, as a Christian, when you see a tree or a human life, how do you explain it?
