Did we have even one law until a point of time and in a given settlement or some villages? Probably not. And we did not have, i suggest, even one priest until, say, 10k to 15k BCE or whehwherever.
And then one priest or two showed up and ever since a kind of chaos or hell descended upon us.

And is still with us today. And haven't you yet espied that no major law can ever be known? And proof is where? In the fact, that if we knew, say, a major law [say, free speech], we would not need judges, lawyers, priests, professional politicians, 'holy' books, law schools....
Btw, i don't know how to log on Agnostic to be able to respond to responders to my posts. Thanks, dear folks!

Theology, or metaphysics, is a fraudulent field of study, religion is a sham, and the clergy know all this. They’ve spent quality time behind the curtain, and are well aware of religion’s pretense. They know suckers when they see them, and continue to succeed in convincing millions that they have a unique channel to truth and enlightenment, knowledge of the divine about which the layperson is, to his/her misfortune, bereft. From their exalted (and physically elevated) position, these con artists and charlatans go by many titles: rabbi, priest, imam, prophet, pastor, evangelist, etc., but there is one thing of which we may be certain: they know absolutely nothing more than any other human being about the actual nature of their deity or the so-called mysteries of creation.
