Your point number one: Would you agree that we are "Co-Creators" on this earthly plane? If so, the idea of being the authors of our genes, in the context of epi-genetics is a sound view. If you believe in what Mark calls the true Law of Attraction, the we are co-creators and thus we can have a significant effect on the expression of our genes. That is being an author. No contradictions here.
Point number two: You are clearly hung up on the religious idea of God. Just because Mark didn't, in this particular lecture, invoke the word God, doesn't mean he is, be default, invoking Satanism. And the idea of the Anunaki being presented in the lecture is just that an idea to be explored. Mark ad nauseum, tells the listener not to take his ideas as the truth, go look it up for yourself and draw your own conclusions. Again, doesn't make him a pusher of Satanism.
Point Number three: Again, you are way to hung up on the religionist connotations of God and the Devil. What Mark is saying is that the Devil is not man with pointed horns, festering out of the lower earth realms manifesting on this earthly plane, as there is no bearded man in the sky (heavens above). Mark is saying that the devil is our own erroneous mis-identification with the false self, the egoic mind. In our ignorance, our mis-identification with our roles we play on this earthly plane, that we are ignorant to our true spiritual nature.
As the rest of your argument is predicated on these initial points... I will spend any further time discussing the rest of your post.
