Is there any proof that aliens really exist?
Probably not. Any such proof would be front-page news for quite a while. The notion that there are widespread government conspiracies to suppress the evidence is rather tinfoil-hat weird. On a related human-interest note: My uncle participated in the original Roswell nonsense (Dr. Charles B. Moore): he was a scientist doing high-altitude experiments in New Mexico with weather balloons, and has been interviewed and responded extensively about the facts in the case for many years. (I trust him, he’s a solid and unpretentious person.) If my uncle Charlie says it wern’t no dang aliens, that’s good enough for me. He also held the world balloon altitude record for many years, but I think its been broken now.
No concrete evidence. No proof. If they do exsist, and chances are they do, (the universe is too big a place for life not to exsist elsewhere) they havent’ visited up yet, or they have, but not in a conventional way. Maybe we’re not looking in the right way. They may be here in the form of something we cannot technologically comprehend yet. OR YES…..ME!
As Stated there is no definitive evidence that aliens exist. There are millions of galaxies each containing millions of stars so there is probably life out there. Although only planets in a narrow band called the habitable zone (were liquid water exists) around sun like stars can support life. Even though there is prob intelligent life out there it prob would’nt have made it here yet as the nearest star to us is over 4 light years away! the nearest earth like planet (planet 5 times bigger than earth in the habitable zone) recently discovered was over 20 light years away.
