Sorry, I miss typed--Yes I mean Zacariah.
But will all due respect, your view of his work is a little broader scope than fair.
The idea of "translating" all these hieroglyphics is misleading in the first place. He is demonstrably wrong on a number of important detail points (the 3500 year period being one of them).
But, that said, the planet has been visited on a regular basis over hundreds of thousands of years and maybe longer. The fundamental thesis of a specific group being the most recent is probably acceptable although they were not the only EBE's (Extraterrestrial Biological Entities) present at any given point in time.
The additional planet analysis seems to stand up--if more informed analysis turns out to be correct, we should see some real signs in the next thirty or forty years.
As a fundamental Christian, I have no difficulty in believing that God created a bunch of other huminoids in many different places; I see Jesus Christ as fairly separate from the EBE visitors--the historic record of who the players were and what the motivations of the actions were is confused. But Christ was real; and His message as enunciated in the Sermon on the Mount is God's description of righteous non sinful conduct.
Sitchin didn't have any idea what he was doing, his 'translations' were just made up. He was a fraud.
I concur about the possible visits to Earth by ETs/EBEs. And given the perceived crash rate of about once a century, in the 4.5 billion year existence of Earth, there may have been as many as 45 million UFO crashes. Kind of a lot, really. But any such critters didn't come from other planets in our Solar System, they've come a long, long way, from a lot of different places.
"To consider the Earth as the only populated world in infinite space is as absurd as to assert that in an entire field of millet, only one grain will grow." -- Metrodorus, 4th c BC Greek philosopher
"Heaven and earth are large, yet in the whole of space they are but as a small grain of rice. How unreasonable it would be to suppose that, besides the heaven and earth which we can see, there are no other heavens and no other earths." -- Teng Mu, 13th c AD Chinese philosopher
