Alien Humans only Scenario

 

Alien is one of the creatures that is still a big mystery now, a creature thought to have come from another planet. Alien is one of the creatures are said to have exceptional intelligence and highly advanced technology.Search alien even been started since 57 years ago, when scientists Cornell University, Frank Drake directs the radio telescope toward the stars and expect transmissions from aliens.Stephen Hawking on 4 February 2008 had sent a message into space whose contents song one of the Beatles song "Across the Universe".But there was never any answer, There is no valid evidence and real facts to support that aliens exist.
Here are a few of these scenarios that made scientists to support the fact that aliens exist:1. MarsThe closest planet to Earth ever considered that the most likely aliens living on this planet because the planet has water as the key of life on the planet, and scientists do a search on this planet and the result is still zero.
2.EuropaOne of the satellites of the planet Jupiter has radiasa on the surface that can destroy living organisms but beneath frozen oceans there may be types of microbe life. unfortunately still not strong evidence that exists.
3. Enceladusplanetsaturnus mini satellite has a supersonic gas and dust that were fired from the surface. This is an indication of liquid that sustains life.
4.TitanTitan is the largest moon of the planet Saturn and Titan has a liquid as the ocean but containing liquid methane.
5. exoplanetScientists use telescopes that can detect the presence of the atmosphere on the planet's surface-Palnet. but yet still limited search.
6. EarthWhy on earth? scientists are also looking at the whole world because of them often seen on earth with operational disks but aliens ever recorded on Earth today is not also prove that aliens exist.
7.Sinyal RadioEfforts of Frank Drake continues with a number of scientists combed the space by using a transmission to look for transmissions from aliens.
