Science reverse engineered us to nothingness (not a natural state). Science theorized space-time warps (something I’m sure we both have a vague understanding of). And you question the possibility that actual history and evidence (as we interpret it) could be inconsistent? You speak of time being relative to another observer… do you think we’re talking about the two trains passing thought experiment or something? And, what other observer… we’re talking about God creating the universe.
One thing physics has not done is "engineered us to nothingness", the big bang doesn't address time zero or where the initial substance of the universe came from, just how it developed from there.
Time/space warps aren't simply theorised, they are clearly in evidence. It wouldn't be possible to maintain the time on GPS satellites or pilot probes between planets without accounting for relativity.
By evidence I'm talking about all the usual evidence of historical events and billions of years of geology and biology.
Now with different frames of reference you can create a different perspective of time passing, but that doesn't make events over time disappear, just apparently go faster/slower.
So if you assume that from God's perspective the time on Earth is only 6 days, 6000 years or the blink of an eye, that doesn't make the billions of years of Earth's history not take billions of years for things on Earth, just not seem so long from the slower perspective.
I’m saying we don’t understand it. So, your timetables could or could not mean anything when it comes to God’s creation.
There being some mysteries and some things that aren't known for sure doesn't remove the ability to know anything at all.
You can't reasonably take the fact that time is more malleable and mysterious than our conventional experience would tell us as a way to dispute any event that occurs in time as unknowable and unreliable.
I remember a quote about this kind of phenomena:
"...when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical, they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together."
--Issac Asimov
You are the one bringing up time dilation as a solution to your preferences about history being not supported by evidence... can you be specific about what elements can be perceived differently in light of time dilation to support your conclusions?
