Why do we see lightning before we hear thunder?


We see lightning first, because light travels faster than sound. Think of it like this, when you're watching fireworks, what happens first, seeing the bright lights of the fireworks or hearing the loud boom? Of course, you see the fireworks and then you hear the boom from them. Lightning and thunder work in the same manner.
