The idea behind Enochian magic is that Enochian is the language that God spoke the universe into existence with. This actually isn't too far off from some theoretical concepts of a "mathematical universe" or "mathematical monism" where all of reality is an emergent property from some sort of algorithm, essentially a computer simulation of a virtual space. If the code is written in Enochian, and we can hack the source code of the universe, then I think that would provide some evidence for the existence of God given that Enochian was supposedly given to man by angels on behalf of God. Currently, though, "evidence" of the efficacy of Enochian magic is indistinguishable from magical thinking and apophenia.
That's Šayṭānist to you . . . anyway, the video is hosted by a bunch of new-age nutters, I can't believe anyone would take them without a grain of salt.
