Hehe, I like his smug voice covered by the epic music
Actually I stood through watching this last video without hearing about any reptilians. It's a nice review of some modern theories and ultimately stakes a claim at an unproven but a marginally possible interpretation of reality.
The last statement about the afterlife is technically congruent with that theory but it's said in a way that will actually mislead people on what this "afterlife" entails.
