So you admit that you don't see the big bang. You see something (movement of galaxies) that (according to you, at least) shows us that the big bang happened. Just like other people see signs that show (according to them at least) that God exists. Difficult?
EDIT:
"The term [big bang] is also used in a narrower sense to describe the fundamental "fireball" that erupted at or close to an initial time-point in the history"
