People in general have a hard time understanding scale for extremely large and extremely small things. It’s easy to understand how far away say, the next city over is. If I needed to quantify it in terms of say, how long it would take to walk there, I could probably make an okay-ish estimate. Trying to comprehend just how far away from us Proxima Centauri is much harder, and if I attempted to perform the same exercise I’d probably be way, way, way off.

People have an easier time comprehending what a billion is. Explaining a trillion as a thousand billion is easier for people (especially average people) to comprehend the scale of.
