The existence of a God has seldom been based on physical evidence; typically our belief in their reality has been based solely on what we were taught as children to believe. This friend I do believe to be a fact, and even if we do not believe in God people will still be born, still grow, and still die. As a species living upon our earth we will still find ways to create and do amazing things, we will also manage to still find a way to kill one another using the most brutal techniques we can envision. None of these things requires a belief in God; they require only the human mind.
