Who knows how aliens think?
While I understand your point about applying human motives and thought processes to an alien race, the fact is that it's a fictional
alien race, and in Star Trek, nine times out of ten an alien is going to think and act the exact same way as a human would.
As for the OP, no, there was no good reason whatsoever for testing the prototype on Earth, unless that place in Florida happened to be the only place on Earth where weapons/ships/other tech, etc. was produced that would have a chance of stopping the main probe later. Obviously that wasn't the case.
