Not sure on what basis you exclude there wasn't anything before Gen 1?
It has never been my position that there wasn't anything before Gen. 1. My position is that the darkness of our world didn't exist before Genesis 1. Prior to that, there was only Light/Day. I believe "Time" as we know it, because when God divided the darkness with the Light.
Jesus was clear that there was two orders of extentence.....one place called the ABOVE. One place called the BELOW.
Yes, Jesus is clear. Our world, which has a beginning and an end, is "below", while the World without beginning and without end that God resides in, is above. One is "Of this world" the other is NOT "of this world".
Scripture states as well there are celestial bodies and terrestrial ones (or of the physical order) Everything you've stated in your line above has to do with the physical order. It's nonsensical to suggest there wasn't ANYTHING that had sequence in the Kingdom of God.
Do you believe in God's Kingdom, the "World without End", that "there are celestial bodies and terrestrial ones"? Time is more than just sequence, in my view. My belief is that God created "TIME" as we know it. I have a "Yesterday, brought about by darkness that divides the "day" from the "Night". I hope for a "Tomorrow" who is brought about by darkness that divided the Day from the Night. I cannot exist in the past, nor can I exist in the future. But I believe God exists in both.
If there is NO Darkness, what remains is only "DAY". No "yesterday", no "tomorrow", only today, forever. How many hours in this day? Can it be measured? And if not, why are you calling it "Time"?
Look if you can accept there was no beginning with God you can likewise accept he had sequence of things whatever they might be all throughout eternity. You're choosing not to accept this is merely bias.
You are assuming that existence itself is proof of "Time". I make no such assumption. How old was God before HE created the Heavens and the Earth? Is HE older today, than when He created our world?
What effect does sequence of events have on God? Does HE get older? Was HE younger? My point is that God doesn't exist in the same Realm as we do. Time, as we know it, has zero influence on God. He exists outside of "Time" as we know it. It is HIS Creation,
everything within our world is influenced by Time. Nothing in the Kingdom of God is influenced by Time, according to Scriptures, in my view.
And if "Time" has zero influence in God's Realm, how do we know it even exists in God's Realm?
I am fine with believing God created "Time" as we know it, and I'm also confident in the belief that God "transcends Time", lives in a realm where Time, as we know it, influences nothing, means nothing. A place where there is no evidence of "Time" at all.
Just as there is no evidence that "Time" existed in God's World before He separated the Light from the Darkness.
There is a vast difference between living a really long "Time" and "living forever", in my view.
