No I just misunderstood you, or you didn't express your thoughts well.
We can measure how far the galaxies are away. I can't explain it to you, I heard it explained and I understood it. Something to do with measuring the angle of observation to that galaxy 6 months apart while earth is on opposite sides of the sun.
Now, we can do that with every galaxy out there visible and we have ourselves a fairly accurate map of the universe.
We can see the way each of those galaxies is traveling, a rough idea of their speed and acceleration, and from there it's just physics. They're all flying away from a focul point apparently.
That is as clear as I can articulate it.
The picture itself isn't of the big bang. But for you to demand that is absurd. Particularly as a creationist. And a christian. Where is the video of the lifeless body of Jesus asending into heaven? Where is the picture of god creating the cosmos?
If you want to come in at this late hour as a christian and stand on the shoulders of secular science and say "ah ha, that's how god did it." Well no one can disprove that.
We can explain everything in the universe and the universe without a god. And putting a god into it adds nothing.
What is your point? I still don't get what you're trying to argue? Other than semantics.
