If we already know the conditions of various planets and moons, why can’t we recreate them on Earth to use to build probes for them?

We already do this extensively. The mars curiosity rover (or its earthly copy) was driven through rocky desert terrain a number of times to see how it would perform on mars. The new mars helicopter was flown in a large, sealed chamber where they made the atmosphere just as thin as it is on mars and used a rope to take some of the weight off to simulate mars gravity.
