If People Tend to Think That the Religion They Follow

is the only correct religion or only their denomination or sect of some religion knows the truth, then there is an impasse. The followers of the religions you think are incorrect think the same of your religion. That would be OK, as long as people didn't get all testy and stuff about others following the wrong religion.

But, in general, people do get all testy. They puff themselves up like small birds do, and try to intimidate the followers of those wrong religions. Or, they insist on proselytizing to those followers, which never works out well. Eventually enough people get all puffed up and start fighting with the others, or try to move into the others' territories.

All in support of invisible deities nobody has ever seen and for which there is no evidence of even existence. When faith leads to warfare, terrorism, or bigotry, such a faith is harmful and useless, it seems to me. What is the point of it, really? How does such religious faith benefit any society or culture?

What sort of deity would encourage such behavior? I mean, an omniscient deity would know automatically that it's a bad idea, right? An omnipotent deity would make its followers not engage in such behavior, correct?. Why do people believe that their deity wants them to harm or even compete with people who prefer a different deity? It makes no sense, whatsoever.

Personally, all that has led me to the conclusion that there aren't any deities at all. It shows me that humans, in their territorial zeal and illogical minds, create deities which think it's OK to kill strangers and take their land and property. All of the deities I've learned about seem far too human-natured to be deities at all. So, I discarded believing in such things.
