IS THERE LIFE OUT THERE?

Humans have always been evolving, and one of the things that are good about that evolution; is the knowleadge we have gained. Oe of that knowleadge is the factthat humans are part of a universe. The universe is so big, humans only live in one galaxy, and there are millions of galaxies; so, humans have always had this question: “Are we alone?Are we the only ones in this universe?” Some people believe that it is mathematically impossible that we are the only living thing on the universe. On the other hand, some people believethat if there was life out there we would’ve already know.

Nasa, is the biggest company of outer space investigation, recently they found a solar system 2.000 light years from earth, 6planets surround the sun, 5 of them are made of rock but one of them is very similar to earth and it has an atmosphere.

Throughout time, strange sights have been reported as UFO’s(unidentified flying objects). In 1254 a mysterious colored ship was supposed to have appeared on top of a church in England. Over the last 30 years at least 100,000 people have reported UFOexperiences.

An astronomer reported he had recieved a message from the stars. He tried to reply during 3 years, however, he never recieved an answer. SETI a company of investigation ofouter space has not found an indisputable life in space.

A physicist named Enrico Fermi considered the question of life in space many decades ago. He came to a conclusion that if alienlife existed in this galaxy; then it should be here by now.

In conclusion, life on other planets is a continous argument, and it will not stop until someone actually sees life on otherplanets; but who knows; there are millions of possibilities that there is life out there.
