The temperature of Mars is minus 60 degrees. Is Mars habitable?

Not only is the temperature a problem, the key is that the atmospheric pressure of Mars is too low, less than 1% of the Earth's atmospheric pressure. As a result, if we don't wear special space suits, human blood will boil (blood contains a lot of water) ), people can't live for more than a few minutes...

So it's too early to talk about livability now!
