In my opinion aliens from far planet look like people. They have the same form ob body and similar color of skin, but it looks more white. Their skin is very strong and it is very hard to hurt them. This "people" are taller then people from our planet and they have silver colour of hair. Their eyes are grey and as their hair they can shine ih the darkness. An intellect of this aliens is more higher then our. It helps them to invent very difficult machines and no one person from our planet will not understand this. This "silver people" eat only fruits, which shine in the darkness too.
