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

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.

Myconids from Beta Brahe or not, I find our first peeks into the culture Arkaim and surrounding cities belonged to and the the area to be fascinating. Maybe it is more so personally because one of the "heresies" I believe is that the isolation of East and West to actually have been relatively recent and short lived. I see Arkaim and some other finds to be inching archeology toward that fact.
