So this was after the eruption of Jesus from the grave, OK. So, decades after God returned to heaven, is that the best you got?
No, I do not know that. I do know that godless principles have been projected out into the universe. Remember, though that light moves at the speed at which God wills it to move. That is the actual and precise speed of light. Not only that, but light exists because God said let there be light! That was something like 6000 years ago and no light in this universe predates that, because no light even existed! Looking at light move now at whatever speed God ordered at this time for it to move cannot tell us anything about great ages. Nothing. Cosmology is a complete fraud that is based on false premises. In pretending they can see so far they prove how shortsighted they actually are! They see nothing but some lights and they add godless assumptions piled to the clouds to arrive at so called ages and distances. Everything they base distances and and ages on in the universe is a lie.
No, you are too busy used false premises like the 'naturalonlydunnit' to attribute creation to the creator. That is very supernatral and no accident whether you know it or not. Basically science is demon possessed! (much of it). It is demonic to look only at the physical and natural processes and world to determine where man and creation came from.
How much would accurate in 6000 years would be the outside maximum limit for your dating techniques. And almost certainly it is far far less than that. If God affected things when Jesus was here, or at Babel, or other times, we would not know.
