Earth has only one moon (its natural satellite), where as mars (2), Jupiter (63),Saturn (31), Uranus (27), Neptune (13), Pluto (3) ! Does any scientific theory explain this trend? Off-course Mercury and Venus has none.

I'm sure there's a large chance element in it, but one idea for the pretty clearcut difference between the inner "terrestrial" planets and the rest is explained at the following link:

Earth's moon is truly unique in our solar system, in terms of their relative masses. No other planet/moon ratio in the solar system comes even close. We're more like a binary planet with the moon with a significant gravitational interaction between the two that doesn't happen anywhere else in the 'hood. Interesting, too, that Earth has never been able to lock in a wandering asteroid into a permanent orbit, like the outer planets seem to have accomplished.

I'm jealous lets go steal one from Jupiter and stay away from Uranus.

It's just the way things worked out based on the size of the existing one.
