If looking further into space means looking back into time, can you theoretically see the formation of our galaxy, or even earth?

I mean, if we can see the big bang as background radiation, isn't it basically seeing ourselves in the past in a way?  
I don't know, sorry if it's a stupid question.

The stuff that we're seeing in the distant past is also really far away.  To see something, say, a billion years ago, it has to be far enough away that its light traveled toward us for a billion years.  So we're not seeing our own past, we're seeing the past of other stuff.

We can't see our own past this way because the light from our past is moving away from us, so we'll never see it.
