Correct on Zacharia Sitchin!I don't know if he's right but he's right but he has plausible theories as to mankind's origins.
I've been keeping track of him since '76. Had the feeling he was painting himself in a corner and would have to extricate himself at some point. Not sure he did it to everyone's satisfaction, but I don't think he lost many fans. Can't believe the number of groups that have sprung up who have used his research to promote their own followings, giving him minor mention or credit, though grudgingly, I suspect -- or even not at all.
