“If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn't turn out very well for the Native Americans.” - Stephen Hawking

Fermi’s Paradox refers to the contradiction between the absence of evidence and the high probability estimations for the existence of extraterrestrial civilizations. There is a huge contradiction between the presumed probability of the existence of extraterrestrial life and the fact that contact has not been made. When Enrico Fermi questioned, “Where is everybody?” the answer was not clear, and it still remains a mystery.

Enrico Fermi was an Italian-American physicist and the creator of the world’s first nuclear reactor. He wrote a paper titled: On the Origin of Cosmic Radiation, in which he proposed that cosmic rays arose through the material being accelerated by magnetic fields in interstellar space. Fermi examined the issues surrounding magnetic fields in the arms of a spiral galaxy. With these systematic researches, Fermi mused about what is now referred to as the Fermi’s Paradox.

This paradox is based on four basic sequential points:
