Why is there no water on the moon?

Why is there so little water, almost none, on the desolate moon, and yet 13 billion cubic kilometres of it on earth? Traditional Science claims earth cooled down by about 3.5 billion years ago, and then the ‘Late Heavy Bombardment’ of comets and asteroids conveniently sprang into action to deliver water by the ocean-full to a desolate earth.

This fairy tale has no evidence to support it besides about 30 holes in the ground to show meteor strikes, and yet has become standard in science because of one reason: no one seriously considered Time could be a Continuum of cyclic processes that never needed this celestial delivery van to arrive with all the water just when earth rang for room service to order it.
