I&amp;#x27;ll personally put all my money into life being found at least fossilized not just in Mars but in europa and anywhere with liquid water, and sharing the same fundamental dna-protein-genetic code makeup as us (but probably little else). The way I see it, once life forms on one planet, it probably starts spreading seeds on a cosmic scale quite promiscuously. The speed at which life arose in earth as soon as conditions were right suggests that there&amp;#x27;s always microbes floating into the planet ready to take advantage.&lt;p&gt;This also would mean that there&amp;#x27;s no opportunity for any other form of life to develop in the same conditions - dna based life probably has a monopoly on water based planets throughout the galaxy</text><parent_chain><item><author>woeirua</author><text>IMO, I don&amp;#x27;t think it should be a surprise that we will eventually find signs of extraterrestial (but not necessarily intelligent) life in our solar system. The real question is: does it share any common building blocks with life on Earth or not?  The answer to that question could dramatically change our understanding of our place in the universe as well as open up entire new fields of productive research in biochemistry.</text></item></parent_chain></comment><story><title>Water on Mars: discovery of three buried lakes intrigues scientists</title><url>https://www.nature.com/articles/d41586-020-02751-1</url></story>
