Do you believe in aliens and extraterrestrial life?  I do!
Yes, like Drake's equation, I have always speculated about the existence of intelligent life elsewhere!
What does Drake's equation state?
The equation summarizes the main concepts which scientists contemplate when considering extra terrestrial life.
So does it prove that there is extraterrestrial life?
Drake equation
The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy.
The equation was written in 1961 by Frank Drake, not for purposes of quantifying the number of civilizations, but as a way to stimulate scientific dialogue at the first scientific meeting on the search for extraterrestrial intelligence (SETI). The equation summarizes the main concepts which scientists must contemplate when considering the question of other radio-communicative life. It is more properly thought of as an
way to stimulate scientific dialogue at a meeting on the search for extraterrestrial intelligence (SETI). The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. The equation is best understood not as an equation in the strictly mathematical sense, but to summarize all the various concepts which scientists must contemplate when considering the question of life elsewhere. The Drake equation is:

Drake's proposed estimates are as follows, but numbers on the right
