How can you live on Mars?

it is possible to live on Mars but to do this you would need an atmosphere, and to have an atmosphere you need gases. To make these gases (there have been discussions about this) you would need to build factories to give off green house gases and make an atmosphere, because Mars is extremely cold at night, then we would have to get people to Mars. This would cost billions and would take a long time to build the atmosphere.
