Is there life on Mars?
Have there been any discoveries that suggest the past existence of life on Mars?
There have been some intriguing discoveries. For example, a rover found evidence of organic molecules in a sample taken from a lake bed in Gale Crater. Additionally, another rover detected methane in the Martian atmosphere, which could be a potential sign of biological activity, although there are non-biological explanations as well.
