Religion is the greatest scam of all time. Good video comparing the striking similarities between Egyptian Horus/Isis story and Judeo-Christian God/Holy Spirit/Jesus.
From Cobourg Atheist:
In the year that Jesus was supposed to be born, there were some common beliefs amongst people in the middle East and if you wanted to recruit followers you had to have your religion have the same features. It’s no use saying – “Follow us, we believe in loving your neighbour as yourself”. You had to have some neat things that showed your founder was a god. And better still, have features that existing religions had so recruits would not have to give up on stuff. Not all early Christians followed this line but those who didn’t had their books burned or heads cut off by Constantine or both. (Cobourg Atheist article)
