Extraterrestrial life

Extraterrestrial life, also called alien life (or, if it is a sentient or relatively complex individual, an "extraterrestrial" or "alien"), is life that occurs outside of Earth and that probably did not originate from Earth. These hypothetical life forms may range from simple prokaryotes to beings with civilizations far more advanced than humanity. The Drake equation speculates about the existence of intelligent life elsewhere in the universe. The science of extraterrestrial life in all its forms is known as exobiology.

Vsauce, Micheal explains if we as a species, are ready for alien contact, and how we would goabout dealing with such a historical event.

It is naive to think that we are only in this vast universe. It's even more naive to think that we are the only lifeforms in our galaxy. There are 6 billion people on Earth, 8 planets in our solar system, millions of solar systems in our galaxy, which is one of the billions and trillions of galaxies scattered throughout the universe.

Who knew who/what to model aliens after? Who came up with the prototype alien that is there when the page loads?

Sussle is the first, open visual encyclopedia. Anyone can use it.

What's a visual encylopedia?

It has beautiful images and viral videos that are way more fun than reading all the text in traditional encyclopedias.
