I read that book when I was maybe 12 yo. Also, ancient civilizations since the dawn of time recorded images of deities (to them), that can be interpreted as visitations, since the craft they rode in on are also recorded in these images. And the ancient tomes of religion, both in the West and the East, mention it. Yet institution knowledge calls this myth. As you mentioned with authority, our controllers keep the generational masses distracted, and nothing has changed. Our controllers are full of shit.
