Cosmic Query

According to news in the popular press, scientists using the Hubble Telescope have observed light from quasars that emanated 12.8 billion years ago, less than a billion years after the big bang.

If it took the light from these quasars 12.8 billion years to get here (presumably at "the speed of light"), how did we beat it here?

We (including earth, the solar system, our galaxy) were presumably products of the big bang. If the big bang occurred less than a billion years before the events we are now witnessing ... shouldn’t that light, that "wave front", have passed us long ago?

How did we get here before the light did?
