Now this is what science is about, drawing conclusions from sound observations and no wild speculation.
we use parallax to determine the distance of the closer stars to earth.

however, at 1+ billion light years, we cannot measure the angular shift differential to compute the distance accurately. so we have to use other methods to determine the distance beyond that.
