Actually, there's a more "logical" and canonical explanation in christianity. Moses broke the first set, and so he went to god and asked for his commandments once again, and god gave him the second set. In all technicality, the first set which christians always boast about was never even in play.

If you look at the link I gave you, it's very clearly explained in the answer, better than I could explain it. But the gist of it is that Moses wrote what was inscribed on the first tablets again, and then God told him some other things that weren't written there.
