Yeah but he was right about Chewbacca. Why didn't that homie get a medal too?
Star Wars had too many people and too many hominid creatures. Life on other planets is likely be viruses, germs, slimemolds, etc.
And now Cark is out there among the billions and billions ... I did watch his COSMOS program regularly though. Surprisingly, his explanation on dimensions has aided me in explaining what happens in The Rapture. Who woulda thunk it!
*** Star Wars had too many white people:***
But the movie was full of all sorts of aliens! And not just illegal ones put outer space ones!
