As of yet, none that is convincing, only tantalizing. The #1 question astronomers and other scientists would like to know today is: "Was there ever life on Mars?" Future robotic missions, and inevitably, men landing on Mars, may answer that question.
No. There is no evidence of life on Mars, and certainly not intelligent life.
No. There is no evidence of any life of Mars, certainly not multicellular life.
There has been no evidence found that there was ever life on mars.
Yes.
Not yet.
Currently, Earth's neighboring planet, Mars is being tested for the evidence of life.
There is some evidence that suggest that mars may have harboured life in the past and possibly still does today. However this evidence at best suggest that life on mars is simple single cell life such as bacteria. There is no evidence what so ever that mars supported large multi-cellular life. It is highly unlikely that anything as complicated as an earthworm never mind dinosaurs ever evolved on Mars.
So far, scientists, who are still hoping, are turning up empty handed on the "life on Mars" subject. There is currently no evidence of life on Mars.
Only robot probes can land on mars. But there are some evidence that is needed to be cleared
No, as of yet there is no evidence of any life existing on Mars but they are still looking.
There probably was life on Mars, since evidence of water was discovered on the planet. However, there is no certainty that there was ever any life on Mars or other planets in our Solar System.
The topic of life on Mars has been one of hot debate lately with the recent Rover bot finding more "possible" signs of life on Mars. However, there is no definitive evidence that there is life on Mars.
