no
Yes it does.
No. Mars is too cold for human life and the air is not breathable. There is no magnetic field to shield against solar radiation.
Yes, there is oxygen on Mars. However there is not enough to support human life.
Because Mars does not have an atmosphere suitable for human life.
no where, but there was a machine that had went to Mars and was said that there could be life in Mars... :)
No. Humans only live on Earth. There is likely no life at all on Mars.

Because there is no water,oxygen,food.
mars is not terrestrial enough to support human life inthe easy way like earth does...
Nothing. There is no evidence of life on Mars. Considering that spacecraft from the planet Earth have landed on Mars, we human beings from Earth are the Martians.
because barnacles are blue
If you were to just put a person on Mars, then no. There is no oxygen on Mars, and oxygen is essential to human life. However, if there were buildings which could provide the oxygen, similar to a space station, and there is plenty of food, then yes it is possible for a human to survive on Mars.
Gravity isn't necessary for human life, as we can see on the International Space Station, where crew members spend months with no gravity at all. But even if gravity were absolutely essential, that would not be a problem on Mars, which has plenty of it.
