There is no liquid water on the surface, and no appreciable water vapor in the extremely thin atmosphere. This, and the generally frigid temperatures make it nearly impossible for Earth-like lifeforms to exist in natural conditions there.
Mars and Europa both have evidence of liquid water, which is essential for life as we know it. Water is a critical factor in supporting life because it provides a medium for chemical reactions necessary for living organisms. This similarity to Earth makes them potential candidates to support extraterrestrial life.
Because Mars is near the habitable zone of life for a star system, it has an atmosphere, and it has water on it, and water is essential to life.
It is unlikely that Deimos, one of the moons of Mars, has water. Deimos is a small and rocky object with a very thin atmosphere, making it unlikely for water to exist on its surface.
The jury is still out on that, but based on careful and thorough analysis of samples collected from Mars so far, the majority scientific opinion is that it's unlikely.
Earth is not smaller than Mars, Mars is about half the size of Earth which makes Mars is smaller than Earth
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.
The characteristic of Mars that is visible in all four photos is its reddish coloration, caused by iron-rich minerals in its soil.
Mars is the planet that is least unlikely to be visited by humans
yes
Mars
It is possible, but unlikely..Although we now know that water is present there..
Unlikely, as it is now, there is insufficient evidence to support the presence of liquid water which means there it is higly unlikey that that Bigfoot lives on Mars.

Mars. The high iron oxide content in the soil gives Mars its reddish color.
100% of the surface of mars is land. There is no surface water on mars
It is extremely unlikely. Coal is derived from the carbon in organic matter, mostly plant material, that is buried deep underground. So far we have found no direct evidence that Mars ever supported life. If it did, that life was probably not present in large enough amounts to leave behind coal deposits.
There are no animals on Mars. It is void of any life.
