Since 2012, NASA's Curiosity, the first rover to ever explore such ancient remains, has already detected the presence of simple organic molecules which can be formed by geological as well as biological processes. However, the emergence of primitive life forms, as hypothesised by scientists, initially requires environmental conditions favourable to the spontaneous organisation of these molecules into…
