So if we see a star exploding that shows to be more than 6000 light years away from us, or however old you think the universe is, was it created during the 6 days and then blown up right after that or when did it explode?
I have no idea, because there is no way of telling what the rate of expansion might have been or whether it is still continuing today.
One must remember that the light we receive in our telescopes today cannot tell us what is happening today in the universe but only what happening in the past. How far in the past depends on the assumptions that are made and those assumptions can not be validated due to our inability to know when things happened in the past.
Vicious circle.
