Aliens Attracted to Earth in the Age of Dinosaurs: Recently, Cornell University astronomers have made a startling revelation. He said that Earth has always attracted aliens, but during the time of the dinosaurs, extraterrestrial life may have been more attractive.
Researchers studied 540 million years. In this study, the Phanerozoic period (three epochs – Hadean, Archean and Proterozoic) was extensively studied. Researchers have discovered biomarkers to detect life on other planets in the universe.
Among these biomarkers, two are very important, one is methane and the other is ozone. In addition, there is oxygen and methane, which arose between 100 and 300 years ago. Both these gases are said to be responsible for the greenery on Earth. Due to this, the amount of oxygen in the Earth’s atmosphere increased.

Researchers have also hypothesized that Earth’s atmosphere was much cleaner during the dinosaur age than it is today, which may have attracted extraterrestrial life to it. Scientists say that over 400 million years, oxygen in the Earth’s atmosphere has decreased by 16 to 35 percent. This phenomenon is also called ‘fire wind’. It is for this reason that in the age of the dinosaurs life on Earth would have been more attracted than it is today.

Like the aliens, Earthlings are also busy searching for life in the universe. Scientists and researchers are engaged in a collective effort to identify light fingerprints or transmission spectra on many planets to determine whether an atmosphere exists to support life. Currently, scientists are busy searching for life on exoplanets with the help of several latest instruments like the James Webb Space Telescope (JWST).
