Absolutely right, nonsense.
There are only two historical strains of religious tradition and their many permutations. Christianity and paganism. Let's trace them back, shall we?
Christianity is a direct product of Judaism, the root of ethical monotheism, which was always an odd sore thumb in a polytheistic society. Christianity also began trimming old pagan holidays' limbs, amputating them out of(mostly) existence. For good reason, they sucked. This was intentional and also wise for marketing purposes and it worked!
Buddhism came out of Hinduism's asshole, nearly word for word. And before Hinduism we have basic ancestor worship(Shintoism et al) and before that the nature cults celebrated for millennia in most cultures. They are all derivatives of one another at this point, cultures sampling other cultures.
Islam is unique but makes a lame attempt to claim Biblical scholarship while at the same time contradicting it. Moses, for instance, was not a contemporary of Abraham. It's timelines are all fucked and it reads like poorly lifted work as if someone took the bible and fed it thru a woodchipper then glued all the pieces back together, leaving all the sense out but keeping all the mighty 'thou shall not' formalities. Basically it's an entirely made up yarn.
Christianity is a fulfillment of Judaism, a continuation of it using prophetic pinpoint precision to the point where certain books of the law and prophets are not read in synagogue anymore because of its self-indicting nature.
So basically just paganism and Christianity and their permutations. One, an earth cult of recycling trends, the other a more linear understanding, non-cyclic, and believing in eventual denouement or the running down of history to a terminal point. One is natural, the other supernatural. One, earthbound, the other based off of revelation, not earthbound.
