I am a believer in aliens.  The science of alien life is called exobiology
I have never heard of exobiology but I do believe in aliens
There is a theory called the Drake equation.  It is a position that covers the existence of intelligent life elsewhere in the universe
What does the Drake equation conclude
It is a equation that allows for estimation of the number of alien civilizations in the Milky Way
And how many civilizations does it think there are
I am not sure.  I do find it interesting that up until the 1920s most people thought the Milky Way had all the stars in the universe
Wow I did not know that.  The milky way is quite large
Milky Way
The Milky Way is the galaxy that contains the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term "Milky Way" is a translation of the Latin ', from the Greek (', "milky circle"). From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within.

Extraterrestrial life
Extraterrestrial life refers to life occurring outside of Earth which did not originate on Earth. Such hypothetical life might range from simple prokaryotes (or comparable life forms) 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.
Since the mid-20th century, active ongoing research has taken place to look for signs of extraterrestrial life. This encompasses a search for current and historic
