Corporate religions produce people of same mentality. The most fundamental error of all religions is that none of them was courageous enough to accept that there are things which we don’t know. They all pretended to know everything, they all pretended to know that they were all omniscient.... hence gave answers from their own minds. For example, Jesus linked diseases with evil-spirits. (Matt 12:22-28; Luke 13:16) He lamented on the behavior of other people (Mathew 11:21; 23:37), resorted to name-calling (Luke 13:32) ... etc., which are definitely not the evidence having divine/perfect knowledge of handling things effectively.
Because religious leaders gave human answers there arose conflicted religions. What a chaos it could have cause if everyone followed same attitude—then we would have had an Islamic physics, a Hindu physics, a Christian physics …etc
