What clues can mean the life on Mars, even if it disappeared from a long time?
Thank you Gian Carlo Visani Italy Answer: Well, the most obvious long lasting clues might be fossils of some kind. Most of what we know about the early biology on Earth comes from traces left in the fossil record. Even if shells or micro-organisms are not preserved as fossils, certain kinds of chemical traces could be strong evidence for ancient life on Mars.
