It is classed as 'something'. Maybe we are an experiment of an alien race?
Back in Jesus time the Earth was flat, and the sky was a dome over the Earth. Now we know that it is round to our understanding (although flat in space/time), and we can now see back 13 BILLION years (You can't fiddle red shifting, same as you can't change Carbon-14).
Why would anyone bother putting all that in place? Spare time? Bored?
