I was thinking yesterday that because religion is so widespread it must be good for the human evolution. If it would be harmful to people from surviving point of view, those believing people would have died long time ago. Now it looks like atheistic people are minority and majority of people are believers. This would suggest that religion has a evolution benefit.
How could it be beneficial? During the middle ages they used to burn non believing people on bonfires, so believing was beneficial. Crusaders killed thousands of non believers?
But Jesus and also other christian people were persecuted and still they survived?
One idea that we need to consider is that God could actually be on their side? What about different religions? I checked wikipedia and noticed that Christianity is leading, but islam is the second biggest religion.
Maybe Christian god is more powerful compared to Islam god? As it’s more widespread? Some say they all believe in the same god. If this is the case, maybe the God is more pleased with the Christian way of worship?
Other way to look it, is to separate religion evolution from human evolution. So religions get better over time and people are just the intermediate, the substance religion is based on.
