      Not necessarily. All we know is that everything seemed to come from a single point, on a cosmic scale. However, at that scale, our entire galaxy would be considered a single point.

      What we do know is that everything is expanding, and that it was homogeneous by the point that it cooled enough to cease being a plasma (and so opaque to light). It could have been a vast area that suddenly spawned matter/energy, rather than a single point.
