Very interesting! Watch this space!!!
I'm looking forward to the November UAP hearing! Let's see if Ross gets onto this.

We have our fairly primitive International Space Station, and plans are afoot to build self-sustaining bases on the Moon and Mars.
It's very conceivable that a more advanced civilization could construct a gigantic self-sustaining mothership the size of a city housing large numbers of beings.
Perhaps they escaped from a planet that became uninhabitable for some reason. Ideas like this have been around for some time.
There could be more than one such mothership and there could be conflicts between them.

The Grudge 13 Report said that the alien that was autopsied had fluid within its body that was a chlorophyll-based liquid which apparently dealt with photosynthesis or similar process. The report theorized that nourishment was taken in through the mouth, however since there was no digestive track or anything of this nature, the waste products were excreted through the skin, hence the malodourous Varginha aliens.

If so you could easily imagine a giant mothership parking itself in orbit around a small star and drawing energy from it like we do.
