Why the moon has no atmosphere ?

Why does moon have temperature variations e.g., from -190^(@)C to 110^(@)C even though it is at the same distance from the sun as the earth is?

If the earth did not have an atmosphere, it would become intoleraby cold. Why?

Escape velocity from the surface of moon is less than that from the surface of earth because the moon has no atmosphere while earth has a very dense one.

Assertion : Two persons on the surface of moon cannot talk to each other. Reason : There is no atmosphere on moon.
