No, but scientists believe that there could have once been life on Mars.
Actually, there is no living thing on Mars (yet), but water is frozen in the polar ice caps and deep underground. So, there is no food source on Mars, but water there is possible.
Mars is not a living thing. There might be living creatures on Mars, and they might have brains, but Mars itself does not have brains. If you are asking about the Roman myths, Mars does indeed have a brain.
Possible as long as we have the technology to create a living environment on mars.
No, a probe is a robot, so it's not really living.
We have not found a good reason that some sort of living thing could not live on Mars. There is water, and the surface of Mars is certainly warm enough. But, no living things have been detected yet on Mars by the several rovers that we have sent to Mars' surface.
Well that I know of their might be living organisms that exist on mars, but aliens its possible.
No, because there is no life on Mars, so that wouldn't be possible, all planet Mars can do is erode and grow smaller or bigger.
No. Water in any phase is not a living thing.
is life possible on mars
Earth is similar to Mars because we know that life is possible on earth and some scientists believe that life is also possible in mars because it has some things which is also present in Earth and is needed for all living things.
No, not without some form of isolation and a great deal of technology
It is not possible to determine the population density of the US on Mars as there is currently no US population living on Mars. Additionally, Mars does not have a large enough population to calculate a meaningful population density.
