So the fact that he made predictions and then told us when they come true it will prove his existence somehow proves his existence?

I predict that sometime in the future the oceans will swell and consume the great states of california and florida. I predict great wars in the middle east and I predict the rise of a great nation in the orient. When this occurs you will know that Ape City is the one and true god and you must put a dollar in the box!
i predict kinky sex in my near future
