This scares me.
I hear ya, but it's only scary because the physical evidence points to the existence of an ancient parent culture that was more advanced than has ever been understood by our current civilization.
Of course, that upsets our established story of humanity's origins in major ways, which can be too far a stretch for some people.
We may never know who those advanced beings were, but there's no question that they were here at some point in the deep past.
I find the whole subject extremely intriguing.
