What kind of evidence has been found on Mars that would suggest the existence of extraterrestrial life?
That's incredible. Is there any evidence of past life on Mars?
There have been some indications that Mars may have had a warmer and wetter past, which would have been more conducive to supporting life. In addition, there have been meteorites found on Earth that are believed to be from Mars and contain possible evidence of ancient microbial life.
