Theists often claim that the complexities of nature and the tiny details that allow human life to exist are evidence of god, as nothing so intricate and unlikely could happen without a designer. I believe that this is not the case as the universe is infinitely massive, and there are thousands, probably even millions of different planets. Logically, it is inevitable that at least one of those randomly created planets would have the required characteristics for life to survive. Can anybody provide a convincing counter argument to this?
