I know my Atheist Advent series of technically over but I’ll share one final video I had bookmarked that I thought addressed one specific issue really well, namely that a big part of the reason that human are religious is that we simply fail to grasp the time scales involved in things like evolution and how they could come to pass over millions of years.
(I’m not saying I’m any better at it either – but at least having a sense of it helps to make things like evolution and therefore, other non-superstitious explanations for our world and how it works, more believable.)
