Most of people on our planet believe in UFO and half of them are sure that aliens have already visited Earth many times. Are you one of them? There a billions of galaxies in the universe that we can see, hundreds of billions stars and an endless number of different planets. Such a vast universe implies sustaining other forms of life. But since there are no official pieces of evidence that E.T. has already contacted us, how can we know or calculate the approximate time of waiting for guests?
Today Smart Banana is going to tell you a secret formula that can help you calculate the odds of finding intelligent life in the universe. So here we go.

The researchers found that about two thirds of studies guess that some 100 advanced alien civilizations might exist in the Milky Way galaxy.
However, the highest estimates come in at 100 million civilizations per galaxy, and the lowest guesses are as low three civilizations per 10,000 Milky-Way-like galaxies. That is a 100-billion-fold difference in predicted abundances of intelligent, communicating beings. So the next time you gaze at the stars and wonder if aliens are out there waiting to be found, flip a coin.

But actually people invented something more smarter. The Drake Equation, a magic formula, which is used to estimate the number of communicating civilizations in the cosmos, or more simply put, the odds of finding intelligent life in the universe.

Just look at it: N = R* • fp • ne • fl • fi • fc • L
