Why is the moon not suitable for human life?

well the moon doesn't have any atmosphere at all, it also is not large enough to maintain an atmosphere. this means there is no particles in the air that can spread sunlight around on it like i nthe other planets. it has water in frozen form but it wll never melt to do the freezing temperatures. the moon also is impacted with asteroids as you can see from all the craters on it, this probably wouldn't be very healthy for people. the moon is a freezing desolate rock, unless we figure out how to terraform .. . we can never live on it
