Not yet.
We have not yet found any evidence of life on Mars, let alone footprints.
No. There is no evidence of any life of Mars, certainly not multicellular life.
No, as of yet there is no evidence of any life existing on Mars but they are still looking.
As of today, we are saying that there is no life on mars. But then again [I don't think] humans have actually landed on Mars [the atmosphere would burn you to a crisp], so we can't say for sure. But no definite evidence of life has been found on ANY planet in the Solar System.
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.
No. There is no evidence of life on Mars.
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.
They haven't found any yet, but they have found traces of water.
There is a formation on Mars that in early photographs resembled the face of a human or primate. No evidence of any advanced life forms have ever been found on Mars. See the link below to view the early images of this rock formation, and more recent images.
Scientist have found what looks to be a place were there was once water so there is a big possibility.
So far we have found no sign of any life, Let alone People, on Mars.
At present we know of no life existing anywhere except on Earth. We know Mars was wet and warm in the past and we are looking there to see if there was life an if so any of it has survived. At present we have not find any evidence but can not yet rule it out. We do not believe that life as we know it cold exist on Saturn but we are intrigued with some of the planets moons, particularly Enceladus as these seem to have warm ocean beneath their surfaces where life (as we know it) may be possible. Again we have as yet found no definitive evidence for life but we feel it is worth looking harder.
