Lots of plausible stuff there, for sure.
I do think the craft are ‘real’ . . . whatever ‘real’ is.
And that God who was angry with them for giving men war making technologies back in Genesis time . . . is even more angry with them for their repeat performances in such matters in our era

And I think that while God is angry with them, he is also using them to his own ends somehow (perhaps in culling those with tainted DNA from his flock).
Speaking of an angry God, I wouldn't want to be in Obama's shoes.;-)
