2. Mars Has an Ocean
There have been discoveries about Mars that say it has an ocean that’s dated to have been existing for around 200 million years. Since Mars is right next to Earth in our solar system, it’s possible it can just as easily sustain life. Another interesting fact about Mars that took it close to the top of our list of the 5 undeniable scientific proof that aliens and extraterrestrial life exist is that even today liquid water exists on the red planet. Water, as we know, can support life. David Bowie asked us long ago if there was life on Mars, and it turns out there probably is.
