I think you misspoke slightly. You would never actually be able to see the BB itself. For some undetermined amount of time after the BB the entire universe was opaque. It was a sea of individual atoms that were still superheated but did not emit light in the former of photons.
Scientists have pretty much confirmed the BB with the discovery of Cosmic Background Radiation which -simply put- is the leftover heat from the BB.

Semantics, I suppose. The goal is to see as close to the point of origin as possible. Just being able to look back to the first light will add validity to the BBT.
At the point of origin, even atoms couldn't form. There was a just plasma soup that was so hot that even the forces of the Standard Model were unified.

But of course this isn't the only evidence. I posted this earlier in the thread.

This is true, for several (hundred?) million years after the Big Bang the universe was opaque.
Horizon documentary on the first stars that formed called Cosmic Dawn. Very well made like all of bbc's stuff
