Some researchers say that the circles were actually used as the runway for an ancient spaceport

I'm convinced of the credibility of this theory.

Sounds good. I'm sure it couldn't have been a military fortification of any sort (just as Stonehenge couldn't possibly be).

It could also be the Freemasons. They've developed time travel - and the cure for AIDS.

The way he adds the thought after more likely explanations suggests to me to be a nod of acknowledgement to someone/some group or a thought spurred by a non archeology reasoning rather than his personnal belief.

Maybe he received access to some site or grant money from someone with such a belief, maybe he is just aware that American tourists with a belief in galactic seeding could visit and make cousin Ashwatthama's/best friend Gregori's new travel tour and hotel chain very successful.

Its hard to say what hes thinking, hes too far away for a mind meld and my cogni-scanner is offline...
