ELI5: When we look into deep space we see the light of stars from deep into the past. Will we, at some point when we can see far enough, be able to “see” the Big Bang?

We'll never be able to see the Big Bang, but we can already see the next best thing.

First thing to point out is that the Big Bang didn't happen at a specific point in space—it happened *everywhere,* so there's no waiting around for a specific moment when light from the Big Bang finishes crossing the distance between its origin and the Earth.

Second thing is that for the first ~370,000 years, the entire universe was still so dense and hot that it was completely opaque, like being filled with a thick dense fog. We can't see anything from before the fog cleared, but we can see the last light from the fog itself, emitted in every direction from every point in space. It's called the Cosmic Microwave Background, and it's visible throughout the entire sky if you have a sensitive wide-field radio telescope.
