I haven't even seen the video yet and I have to take umbrage with some of your points............"If this is such amazing belief-shattering news, that's been around since the beginning of time, why hasn't the story been told already, NUMBEROUS times? Why hasn't modern religion crumbled?"
That's easy..........modern religion usurps your own spiritual journey, lays out a roadmap, makey you stop having to think about yourself and who you really are........life "appears" to be easier when someone takes one of these theologies on. Humans are by nature weak...........so they will gravitate to that which makes them comfortable and doesn't require anything difficult. Religion tells you how to interact with your fellow man, how to judge etc...... so it's very easy for me to see why certain religions catch on like wild fire in certain regions. It's no coincidence that the people who make/made carreers out of "thinking" and "observing"..........usually discard human notions of god............because they see humans for what they really are, so a book written by humans almost carries no intellectual weight. Religion is for the worker ants...........keeps them sedated. I absolutely whole heartedly beleive in a higher power............but I will never adhere to a human religion.
