Who came up with the idea of how aliens physically look?

Question

Who came up with how aliens look and what time was this created? Big eyes, long and skinny fingers, big heads, etc.

Answer 1

It's just a general human thing to make up imaginary creatures that look like ourselves in some way or another.  It's not so much that people intentionally do it, it's what our imagination does when we don't keep it under control.

Aliens, gods, mermaids, leprechauns, centaurs, etc...

Answer 2

Etheir the hipies or a person that has a lot of time on his hands...Being serious though I heard that the idea came from some ancient drawings on a cave in Africa.

Answer 3

Roswell, New Mexico; July 1946

Answer 4

The people who saw them!

Answer 5

They evolved over time, in much the same way that species do.  In old sci-fi stories, comic books, etc., from the early 1900's, a viriety of alien creatures were generated.  Some were popular and they appeared more often.  Monster movies of the 50's and 60's often used creatures with large heads and long fingers.  A certain style of alien gradually caught on.  There were variations, as there are today, but a general set of characteristics came about by a kind of unwritten common assent.  One alien form was more successful and more artists copied it.

Answer 6

the people who hav claimed they encountered with them, and its not just one person who said how they looked.
