Right up front, I'm admitting that I didn't read much more than the first two "proofs".
But, there seems to be a fatal flaw in their "proofing" that God doesn't exist.
Say that I am not convinced that Bill Gates is one of the richest men in the world.
So I go up to Mr. Gates and say, "I want you to prove to me that you are one of the richest men in the world. Sudan is a nation in which millions of people are struggling with abject poverty and all the wars and diseases that come with poverty. So, in order to prove to me that you are one of the richest men in the world, I want you to give every man, woman and child in Sudan $1,000,000 American dollars. There are only about 42,000,000 people in Sudan, if you are as rich as some people claim then this is just chump change to you anyway. And, if every man, woman and child in Sudan was suddenly a millionaire, many conflicts would go away because there would no longer be poverty and the subsequent spreading of wealth would result in a much stronger economy in the entire region if not the entire continent of Africa. So, Bill Gates, if you don't give every man, woman and child in Sudan $1,000,000 then I refuse to believe that you are rich, because it is so smart to do this, the only way anyone would ever refuse this request is because they cannot."
If security hadn't dragged me away from Mr. Gates by the time I finished, his response to me most likely would be, "Go away, I don't even know you." Then he would go on investing his money and time as he sees fit. My lack of belief in his wealth, nor his lack of answering my demand would have no bearing on his actual wealth or what he chooses to do with it.
