Atheists can afford to make mistakes
Atheism is more trustworthy than theism as it is a concept made by humans and is aware of that unlike theism which is a concept made by humans and unaware of that. Therefore atheism can afford to make mistakes and own up to them as we are not perfect, we're just part of a chain in evolution. Atheists don't jump to any conclusions about how the world came about unlike theism in which assumptions have already been made many many years beforehand and assumptions that need to be stuck by.
