I find these 'you can't answer' videos funny when its clearly setup to be debunked.
Several of these questions were similar to one another, how did life start, how can you have morality without a god to tell you it.
I think the best part was when he said that most religions asking these questions don't themselves have an answer for the questions their asking, like how life began, they just assert they do, thinking an atheist who says 'I don't know' to a question is a weakness, when really its a strength, an opening to seeking better knowledge of something, where as the religious person pretends to know the answer to something they don't, which is a pledge of ignorance.
