Question about Light from the Big Bang

Let me start off by saying that I am just barely aware of the basics of
relativity and in as much I have a question that I cannot seem to find an
answer to. I would appreciate someone with not only understanding but
maybe a certain level of skill for stating things in easy to understand
terms for non psycisist.
I have heard mention that with our advanced telescopes we can see light
that is so far away that it has been travelling towards us since very near
the "big bang", in effect giving us a view into the universe's distant past
and early beginnings. But it is also my understanding that at the big
bang, all matter in the universe was essentially in a single point, this
point including all space as well. At the point of the "bang" matter and
the space containing it exploded outward. Light being a constant speed,
and nothing can move faster than light, how is it that the matter that is
our planet, having started at the same point as everything else, can be so
far away from the light that is coming towards us that supposedly was
emitted near the forming of the universe? Wouldn't light from the big bang
14 billion years or so ago be at the very edges of the expanding space,
farthest from the point of origin?
I would think that in order to see light coming towards us from so long ago
that it was from the big bang would require us to be some 14 billion light
years in front of it to begin with?
I know that my reasoning reflects my lack of study in this field which is
why I have turned to those who could explain it to me.
