The video did point out tha tmost atheists who convert admitted do so while in an emotional crises, and he freely admits that doesn't cover every atheist who converts.

The point of th evideo is that you can't really use rational arguments to get atheists to convert.

I think for some people, it is just that they want to believe their life has some kind of higher puroose which religion provides for them.

I myself have stated many tiems here, that humans are "herd animals" or instinctively form groups, because in our evolution, that was a survival strategy hard wired into use instinctively. So, even though we no longer need to form groups people still don't feel "sage" unless they are a part of a group or community. A sense of community is the one positive thing I admit to organized religion providing people. And, I am sure those who convert, outside of an emotional crises, seek to have that sense of belonging to a community because it is hard wired into us instinctively. A kind of residual instinct, which not needed in today's society all that much, is still there.

And yes, I do see some irony in that the very thing (instinct for a sense of belonging) which brings people into religion kind of helps argue for evolution, and posits that religion is an outgrowth of our evolved instincts. It is both kind of poetic and tragic at the same time.
