It's an extraordinary claim that there is no supreme being that has set everything in motion and has created everything. I can look at the ground and only see the ground, not the whole earth. Just because I can't see the whole world doesn't mean that it doesn't exist. Just because I can't see God that doesn't mean he doesn't exist. Everything that brought life on this earth to be what it is today was produced by extremely slim chances. Luck can't possibly do that. It had to be set in motion by something. It's an extraordinary claim that there's is no supreme being, just as much as it is an extraordinary claim that there is a supreme being. You need facts if you want to prove that there is no God, but I know that you'll never find complete facts to disprove it.
