There are many wonders of the universe. For example, will human life everevery live on Mars? But one question still ponders even the greatest of minds, is there any life out there? NASA found signs of water on Mars! Anything is possiblepossibly. But do I believe in Aliens... yes!
Helen Sharman, the first British person in space, said she saw signs ofoff life out in space when she left orbit. She also said, "There are so many billions of stars out there in the universe that there must be all sorts of different forms of life. Will they be like you and me, made up of carbon and nitrogen? Maybe not." She's not alone. Micheal Collin, also an astronaut, got asked the question do you believe there'stheirs life outside of earth on Twitter. He said "yes" without any further context.
While we have witnesses, we also have evidence. In 1976, NASA's Viking landers hinted at chemical evidence of life. One experiment mixed soil with radioactive-carbon-labelled nutrients and then tested for the production of radioactive methane gas. The test reported a positive result. The production of radioactive methane suggested that something in the soil was metabolising the nutrients and producing radioactive gas. But other experiments on board failed to find any evidence of life, so NASA declared the result a false positive. Also in 2004, a mysterious radio signal was received by the SETI project on three occasions – from the same region of space! Tell me that doesn't mean Aliens!
Another argument stating that intelligent life is out there. Seth Shostak, a senior astronomer at the SETI Institute and a technical adviser, notes that there is no direct proof for any life beyond Earth, but the universe is home to a lot of stars. And as research over the past decade has shown, perhaps at least 50 percent of those stars harbor planets. Shostak estimates there are 1 trillion planets in the Milky Way alone. "Surely some of them have undergone what Earth has undergone and developed life, and eventually what we call sentient life," he says. The argument, he notes, is simply one of probability. "If we are the only intelligent beings in the galaxy, or for that matter in the universe, then we are truly a miracle," he says.
A lot of people have the idea that there is intelligent life out there. I believe that it is true. Where else would people get the idea of a UFO? And like Seth said, it would be a miracle if we are the only life out there. In conclusion, I believe that with this evidence, there is a good chance of real life out in space.
