Why I find this disturbing
The most intelligent explanation for the Roswell thing is that the US military
was putting on a hoax, because it made a lot of their post-WWII experimental programs easier to hide.
There are plenty of people on the planet with six fingers and toes. (Google on the word "Polydactyly".) They get the corpse of a small six fingered woman and shave her head -- and that is your alien.
It makes me sad, but I keep thinking we were watching a real person getting dissected.
