If I have to sit through this after I die "Hell" is a somewhat accurate way to describe it.
I'm not hardcore religious by any means but this is just painful to watch. It seems modern atheism is well on its way to becoming a parody of itself. This is little more than a session of smug atheists patting each other on the back and stating the notions everybody in the room agrees with. Because a lack of physical evidence aligns with their pre-determined conclusions on all "religious" matters it is somehow scientific? I don't see anything to learn here, there is a lot to observe however. Despite all of the degrees and education of the people speaking this is the same sort of behavior you can watch from clueless Hollywood celebrities during their beloved award shows.
Certainly the world of science can do a lot better to promote itself as "fun" than to serve as some sort of soapbox for atheists to preach views which in most instances cannot be proven one way or another. I know this wouldn't have gotten my attention as a kid, or now for that matter.
