Of course there is life out there Virginia, if you believe in god he is alive along with all his angles good and bad ones. I have heard it said there are more galaxies than there are blades of grass on a golf course, so if that is the case than I am sure there is life that has some stature out there somewhere.
Assuming there is people on a planet the size of Jupiter, well Verginia they won’t look like us they would be big SOB’s with bone structures out the wazoo and muscles to match, all to accommodate the gravity that would be so much more greater, so go figger, sounds kind a like a the Annunaki.
Who were the Annunaki?
Giant hominoids, standing on average 8 foot tall and far heavier and more muscular than humans, visiting Earth from their home planet, termed the Planet of the Crossing by the ancient Summerians.
This planet is known by many names - Niburu, Marduk, Wormwood, the Destroyer, the Red Star, and lately Planet X - but the ancient Sumerians termed it the 12th Planet, as they counted also the Sun and Earth's Moon.
