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 actually means Milky Circle in latin
