Not to go all bible on ya, but....There is an allegorical comment about how long days and years may have been a very long time ago when no records were kept. Peter 3:8.
My Christian brothers and sisters always seem to be at each other's throats about "time". To me it's fairly simple. Isaiah 55:8-9. If there is a God, and He made the Universe, I suppose he could do anything within it that would suit His purpose. Nit picking is always fun, but sometimes, as the old adage says, "You can't see the forest for the trees."
