It was invented the same way religions(something scientists love to criticize) are but people are zealously defending it as if it is the objective way to understand reality. Most people don't even question fundamental things like base 10, this is how anti-intellectual scientists are. When are you finally going to admit that you're just as emotional as religious people when someone criticizes your beliefs? Not only that, most scientists are accepting anything as long as big buck and politics are in play(general relativity).
