I dislike these sites because most of them are rant’s from a athiest’s viewpoints. A lot of the above site is just a person angry at God. The proof’s are very exaggerated; this person is only looking at extremist beliefs.
The author of the site blames God for the world we live in. Instead of saying “I thank God for His tests, His unconditional love and His creations so I may exist” the author is saying “I blame God for this world we’ve created”. God created the world perfect once, and humans kind of blew it.
But understand that you simply cant always understand God. A lot of people are arrogant enough to compare themselves to God, thinking that if they can’t figure something out, surely God cant either. Just because we can’t understand it, doesnt make it any less real. Sort of like quantum physics.
