RE: Where does the carbon found on Mars come from?
Hello @emiliomoron, The two theories that most capture my attention are the possible existence of glaciers and the possible existence of "biological entities", because as far-fetched and fanciful as it may seem, they seem very likely and really make me very curious, because this would be the best proof of "existence of life" on the red planet.
Hi @tocho2, there is certainly a lot of intrigue in the subject, all theories are valid according to the evidence, perhaps the scientists are trying to be cautious with relating the evidence to the existence of life on Mars, we will continue with the intrigue until there is more data to confirm any of the theories.
