Life outside of Earth: why we still haven't discovered aliens

Scientists at the Australian National University's (ANU) School of Earth Sciences Research say there were other inhabited planets in the universe besides Earth. Scientific article published in the journal Astrobiology.

According to scientists, the inhabitants of these planets became extinct due to climate change. The organisms were single-celled, they did not have time to develop to such a stage that a trace of them could be found.

Life could be on Venus and Mars. According to Charlie Lineweaver, one of the authors of the study, microorganisms simply did not have time to adapt to temperature fluctuations. So, Venus turned into a ball of fire, and Mars – into a huge refrigerator.

Due to the fact that life on these two planets was just incipient, microorganisms could not regulate stability on the surface of Venus and Mars, could not affect the amount of park gases. That is why such climatic changes have taken place on these planets.

Another author of the study, Dr. Aditya Chopra, believes that this theory may explain the Fermi paradox. This is when arguments are put forward that there are many advanced civilizations in the Universe, but at the same time there is no evidence of the existence of these civilizations.

NASA recently suggested looking for aliens on the trail of pollution. Modern telescopes are capable of detecting a human-like civilization up to 30 light-years away.
