In case you didn’t know, Carl Sagan, the man behind Cosmos, was a firm believer in the hypothesis that life may emerge from other planets as well. He was confident that he’d discover considerable proof to back this up on Titan, as it was one of the most habitable planets in our galaxy for a reason.
Titan is a massive Saturn Moon with barely enough atmosphere for life to exist there. This is why he began with an experiment that involved simulating Titan’s own atmospheric conditions on Earth. This is how Carl Sagan was able to obtain organic material that verified his idea.
He was ecstatic about the Cassini probe’s 2004 voyage to Titan, but he died before he could view the results. Fortunately, the results were inconclusive, to say the least, so in some ways, it’s better that Carl didn’t get to complete the mission.
However, a new sequence of discoveries in his name have recently taken the globe by storm.
During the popular Rosetta mission, which ran from 2004 to 2014, the Philae probe was scheduled to travel to Comet 67P / Churiumov – Gerasimenko in order to examine the comet’s surface and see what discoveries might be made.
To everyone’s surprise, it appeared that Glycine, the primary building block of nucleic acids such as DNA, had been discovered within it.
This is valid proof that life could migrate from one space to another via comets and meteorites.
As a result, it was believed that life may have emerged on Earth in ancient times as a result of one such comet. This would make us aliens as well, and it would explain how we came to be on Earth all of a sudden.
