Could we terraform the moon instead of Mars?

Terraforming is possible in principle, but remains impracticable with current technologies.

If humanity really wanted to make it happen, it would actually have many advantages starting with the Moon rather than Mars: it would take less money, time and resources, we would have more sunlight, and the Moon is just a few days away from earth.

To produce an atmosphere, we would have to bombard the moon with thousands of ice comets, which would release water vapor and carbon dioxide, along with traces of other gases.

Over time, the gases would form a thin atmosphere, composed of carbon dioxide, methane and ammonia, capable of producing a greenhouse effect sufficient to heat the satellite and allow the presence of liquid water on the surface.

The water carried by the comets would in fact become an ocean, and the new lunar ocean would reflect a lot of light, making the Moon appear 5 times brighter from the earth than it is now.

The large number of asteroids crashed into the satellite would provide momentum, which would result in an accelerated rotation of the moon around its axis. From a lunar day made up of 28 Earth days, to one of only 60 hours. And obviously, the moon would no longer be in synchronous rotation with the earth.
