The existence of extraterrestrial life has been seen as a possibility through the discovery of exoplanets, Kepler missions and mathematical formulas. Others doubt the possibilities of an alien species like Enrico Fermi and Pope Zaccaria. Although the thought of aliens has created numerous cults and science fiction books, many mainstream scientists have begun to devote time and money to finding the answer: do aliens exist?

Given the enormous number of galaxies, stars and planets estimated to be present in the universe, there is a high probability that life arose somewhere besides Earth, and Drake's theory agrees: ( What are the chances that there is life in space?) . In 1961 Frank Drake developed a formula that has been debated for decades (what are the chances that there is life in space?). The Drake Equation estimates the number of potential intelligent life in our galaxy (what are the chances that there is life in space?). The results are widely variable, it all depends on the variables selected, yet it is still one of the best ways to quantify how many extraterrestrials exist in the universe (what are the chances of there being life in space?). Life is a complicated variable on... middle of paper......t%20Our%20Size&res=Y&ren=Y&gov=Y&lnk=Y&ic=N>.- - -. "Kepler's mission is looking for planets our size." SIRS problem researcher.
