why do people think mars could one day sustain life?

People think that because it may have at one time sustained life. There is evidence of canyons and canals that may have had flowing water through them. There are also areas of deep ice, similar to the ice on Europa, that may have water somewhere deep below it. Also, though it gets very cold, the maximum temperature it reaches is around 20 degrees celcius, which is very 'livable.' If there are animals that could sustain the cold, then life could exist, and if and when we colonize space, we could live there too.

Hope springs eternal. We need some place to provide a second location for humans to live in case we do sufficient damage to Earth that it is no longer able to sustain humans.
Sorry for my pessimistic answer.

Because they don't have common sense. They expect us to move to Mars, which would be extremely difficult to colonize, when we're on a perfectly good (and much bigger) planet now. We'd be much better off to not screw this one up. We can't even feed the people we have on Earth now and we can't get along on it now. Who gets to go and who has to stay if we go to Mars? Only a precious few could go. We're better off here.
