We definitely created God, Jahwe and Allah. NO DOUBT ABOUT THAT! Did you hear me guys? Everyone can start me bashing me after the next sentence, so please wait while I elaborate:
What are the chances of the Bible, the Qu'ran or the Thora being completely or even partially right? No more than one in a billion. Why? Because all three of them were written down by human beings. Well, not exactly, human beings who said they themselves were "inspirated" by a superior being. Of course it's impossible to prove this and the only argument they have is their own word.
Add to that their probable shabby mental state. Why I call them crazy? Let's see, how would you define a guy that strolls around telling people he's the son of God? That's right, you would call him a lunatic. So not only is the only "evidence" we have of their writings being correct their own word, it's also the word of a lunatic.
Furthermore they started from scratch. It seems improbable they were inspired by a superior being, as I proved above, so we can accept that. Thus these three religions are based on human invention.
Now may I ask you what's the likeliness of a human invention about a superior being being completely right? Yep, no more than one in a billion billion.
