www.Gaia.com is an incredible resource and is quite inexpensive. I’d recommend
the section on Ancient Civilizations, episodes 1 and 2 which are mostly about
Enki and Enlil, the two most important persons in Sitchin’s The 12th Planet and
other 13 books. Unfortunately none of these experts cannot cross the dots and ts
and therefore miss out on the best explanation/interpretation that I have come across
in 40 years of my own personal research. What a pity!
