Time is relative. To the guy on the edge of a black hole for instance it seems that only a few seconds passed to enter the black hole where to an outside observer it took many years. I guess it all depends on your point of observation.
In order for men on earth to observe the stars expand, men on earth could NOT be part of the expansion, else all would expand equally and there would be no perception of movement.
IF men perceived movement, they must be the center of the universe, because we were not moving with the rest of the universe.
IF we perceive movement (expansion) is our sun part of that movement?, and if so, WHERE was the center of the bang ?
Our minds are conditioned to consider our sun as the center and all of our thought processes subliminally document ourselves (our sun) as the center of all time/creation .. whatever .... yet, we ALSO know the universe appears to be infinite.
I don't pretend to have an absolute argument to conclude for the non believer to believe, but I AM a believer, and the days of Genesis are 24 hrs, no matter WHAT some Kabalist says.
(btw ... if we ARE part of the expansion ... we are constantly getting taller and fatter ... toss the diet ... y'can't win against cosmology ... you're fat fatty fat fat )
