Very dangerous ground for these gentlemen to ponder. If the speed of light was faster in the past, then aging would have occured (relative to what we know it as today) at a rate proportional to the speed differential between then and now.

If you can vary C, then isn't it possible that 6,000 years at our relative C could be billions at a higher C ?

Hmmm. Like I said, dangerous ground the Godless are treading.

If the speed of light was faster in the past, No, it was not: the speed is a number, it does not move.

then aging would have occured (relative to what we know it as today) at a rate proportional to the speed differential between then and now. How would biological processes know that the speed of light changes? Also, one cannot say such things without saying who the observer of such processes is.
