Sorry, but the Christian faith proved its claims with the resurrection of Jesus Christ.
Atheism, however, has shown itself capable of incredible acts of brutality in the former Soviet Union, Communist China, etc.
I see pride still goes before the fall.
Show me the Ark! ;-) Better yet, build me a boat, and put two of all the animals on earth on that boat, for 40 days and 40 nights. If you can't do that, I say that the Flood (that killed ALL the animals and ALL the people on earth, less than 6000 years ago) was just a, "fabrication churned up by fanciful, over-imaginative individuals"!
And after you get done doing all that...answer the question that I've never gotten a fundamentalist friend of mine to answer: What were the races of the people on the Ark? Was Noah oriental, and his wife black? Who was the Scandanavian?
Proved it to who?
