Time is just another of God's creations. "Before Abraham was I Am". So to try to trap God into a prison of 7 days and 6000 years is so so foolish.
Science is struggling to get a grip on exactly what time is.
We are in full agreement.
(And trying to make God a liar by saying they aren't days could be just as foolish: "For the wisdom of this world is foolishness before God." [1 Cor 3:19])
We are foolish, and ignorant, and arrogant -- and that's where God has to start (because He's the one that starts).
