The idea of ​​extraterrestrials is a subject that many Hollywood film producers and writers have been creating successful films and novels since 1902 with the French film A Journey on the moon. The existence of extraterrestrial life has been considered a possibility thanks to the discovery of exoplanets, Kepler missions and mathematical formulas. Others doubt the possibilities of an extraterrestrial species, such as Enrico Fermi and Pope Zachary. Although the thought of extraterrestrials has created many cults and science fiction books, many mainstream scientists have begun to spend money and time searching for the answer: Do aliens exist? The world is full of possibilities. The possibility of extraterrestrial life is defended by scientists around the world. With technological advancements, such as the Hubble Space Telescope, the Kepler drone and numerous research agencies and groups around the world, the search for extraterrestrial life is increasingly supported (Search for Extraterrestrial Life). Given the large number of galaxies, stars and planets believed to be in the universe, there is a high probability that life arose somewhere other than Earth, and Drake's theory is agreement: (What are the chances that there is life in space?) . In 1961, Frank Drake developed a formula that was 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 vary greatly, depending on the variables selected, but it remains one of the best ways to quantify the number of aliens in the universe (what are the chances that there is life in space ?).
