We do know there has been at least a 1000 religions, some estimates as high as 4,200 and that might just be current ones not religions now no longer practiced so we know humanity makes up bollocks about gods with 99.9 certainty as only one can be true if at all. Life has existed for 3-4 billion years on this planet and its been a very long road of evolution.
There is no place for god in reality. Reality is a hard place. The idea of injecting some moral being into what is basically chaos is just ridiculous. If a lion chases a zebra and rips it apart with its foal inside both brutally and painfully killed and consumed no god cares its just a process of survival which works much the same for single cell life or complicated multi-cell life.
Most of us can't be bothered to argue with people who have been indoctrinated to believe these ridiculous stories which are often incredibly strange and clearly heavily influenced by the violence of their times.
I mean the old testament where it has killing people and cutting off their fore skins to give as a wedding present or the bit where children ridicule a bald man only for god to kill the children by being ripped apart by bears.
You can't argue with people who choose what they want to believe rather than look at the evidence. That's basically insanity.
