Op, thanks for your information in this thread.

Are you familiar with the book The Ringmakers of Saturn by Norman R. Bergrun?

In this book, Bergrun presents evidence (including photographic evidence) of large "crafts" appear to be mining (or otherwise manipulating) different planets and moons in our solar system.

To your knowledge, could these crafts possibly be from a past human (from earth) civilization? Or could they be something else entirely?

Any information that you could provide would be appreciated.
