In a way yeah you could say God put them there. Jupiter, the planets, our entire solar system came from a swirling cloud of gas and debris that overtime condensed down into the planets we know today. That is why they are all orbiting the same direction and are mostly on the same planes of orbit. Jupiter has indeed been collecting debris overtime. But anything that doesnt strike the planet gets ejected back out.

I suppose even broom is not quite right. Sheppard would be more fitting. Jupiter, Saturn. All the gas giants are what is responsible for stability. They have given our solar system the stability to allow for life on Earth.

Edit: Just to be clear. Moons and objects can be caught into orbits around other planets but it's usually the result of multiple gravitational influences not just one big gravity well. Then there's other instances like striking other objects. Objects breaking apart and such.
