For several years, people have always claimed for the existence of aliens. Often described with non-human features, these aliens are said to be existing and living somewhere outside the perimeters of the Earth. But a recent study conducted that showed the opposite: experts say no evidence has been found regarding of its existence yet.

Because of the results, researchers say creatures living here on Earth must have evolved early. Earthlings must have been more than 200,000 years ahead, as posted by Express. The findings have crossed out the possibility that there have been existing terrestrial beings roaming around the universe aside from humans.

During the 13.8 billion years of the universe's existence, studies proved there should have been no existing living organism in any part, even on Earth. Evolution of life needs enough time to happen, maybe about 10 trillion years more, as reported by Daily Mail.

Avi Loeb of the Harvard-Smithsonian Center for Astrophysics and the study's lead author said, "we find that the chance of life grows much higher in the distant future." The reason behind is the celestial object's star. Anything that is about to evolve into something living would be more or less dependent on it.

A star is crucial in a planet's formation of life. According to the authors, there are two reasons behind it. First, the sun is the primary producer of heavy elements, which include carbon, iron, oxygen and other elements needed during life cycles. These elements are important in order to have balance in all living organisms.

The second reason is that a star has the ability to produce heat. With the energy produced, chemical changes on the surface of the planet are enabled. In fact, even water is produced by this process.

Researchers say there have already plans to conduct more studies to prove their hypothesis. That is through Transiting Exoplanet Survey Satellite (TESS) and James Webb Space Telescope (JWST). Nearby red dwarf stars will be the subject of their future research.
