Globally all around there is a layer of igneous rock below the other rock, so the Earth was molten at least once. If it happened more times than that, it would all melt and leave no trace. So why think it might have happened, other than it sounds cool or something? Don't get a wild idea and then look for evidence; that's bad science. Find evidence, then look for an explanation that fits it, then test that idea, then find more evidence and explain it, then repeat over and over until all the evidence works together with one set of compatible explanations.

Good question, I can't think of a way.
I also can't think of a reason to think it might have cooled down, then became molten again, then cooled down again. Any process that would do that seems highly unlikely, and notions to that effect probably are purely speculative with no basis.

By examining the layers of stone on the surface of the crust, or possibly below inside a chasm.
