Ancient Gods: Lost Histories, Hidden Truths, and the Conspiracy of Silence, by Jim Willis (2017)

Biblical Archaeology: An Introduction with Recent Discoveries that Support the Reliability of the Bible (2014)
This IS important! As Sitchin uses the HISTORICAL events of the Old Testament to COLLABORATE/CORROBORATE his research from the SUMERIAN clay TABLETS and CYLINDER SEALS. Please try The 12th Planet. His second foundational book, The Wars of Gods and Men, for me, ABSOLUTELY PROVES that Sitchin is not only a GREAT interpreter of the TABLETS and SEALS, but also one of the BEST BIBLICAL SCHOLARS that the planet has seen. STUDY for yourself, please.
