Experts are of the opinion that numerous UFO sightings are really no proof of aliens existence in our world. More so when we don’t have any conclusive evidence of a UFO being closely seen by a group of people in any industrial nation.
Aliens might not exist at all anywhere in the universe. A very prominent astronomer presented a new theory at a conference this week that might confirm that life might not exist on other planets.
Charles Cockell, the director of the U.K. Center for Astrobiology at the University of Edinburgh, claimed in a statement that, “The pervasive nature of life on Earth is leading us to make this assumption. On our planet, carbon leaches into most habitat space and provides energy for microorganisms to live. There are only a few vacant habitats that may persist for any length of time on Earth, but we cannot assume that this is the case on other planets.”
Cockell said that, although there might be many habitable planets in the universe but that does not justify that they had Earth-like-life. “It is dangerous to assume life is common across the universe. It encourages people to think that not finding signs of life is a ‘failure,’ when in fact it would tell us a lot about the origins of life,” he added.
A large number of “extrasolar” planets orbiting stars beyond Sun have been discovered since the 1990’s and with the new and advanced techniques in the recent time, astronomers are able to identify smaller, rocky planets within the “habitable” or “Goldilocks” zones of their parent stars.
Prof Cockell also justified the possibility that scientist may not be able to find any signs of alien life, even if it exist. He further said that life might differ from planet to planet, and that astronomers on Earth may be looking for some other signs of life similar to Earth which is leading in disappointments.
“Professor Cockell explains that in coming decades, increasingly powerful telescopes and developments in spectroscopy may allow us to look for the signals of life on planets beyond our solar system,” the Royal Society, the United Kingdom’s national academy of science officials, claimed in a statement.”However, regardless of this, our view is still going to be heavily influenced by our knowledge of life on Earth.”
Prof Chandra Wickramasinghe from the University of Buckingham said in January that algae found inside a meteorite in Sri Lanka confirmed that aliens do exist.
“These finds are crushing evidence that human life started outside Earth,” Prof Chandra said.”The algae organisms are similar to ones found in Earth fossils but the rock also has other organisms we have not identified.
“We are all aliens – we share a cosmic ancestry. Each time a new planetary system forms, a few surviving microbes find their way into comets. These then multiply and seed other planets,” he added.
“These latest finds are just more evidence to point to the overwhelming fact that life on Earth began on other worlds.”
Jamie Wallis, team leader of the investigation of the Sri Lankan algae and highly respected astrobiologists at the UK’s Cardiff University, said that their study “provides clear and convincing evidence that these obviously ancient remains of extinct marine algae found embedded in the Polonnaruwa meteorite are indigenous to the stones and not the result of post-arrival microbial contaminants.”
