Time is a relative physical property.
Is God limited by the physical or outside the physical?
God is unlimited, and outside the physical. However, His works appear to exist in this world, and appear to behave according to what we call the laws of physics which were authored by God.
It appears that starlight reaching our eyes from distant galaxies has travelled anywhere from a few years to several billion years from its destination in order to be seen by us. Furthermore, the nature of that light shows us processes, such as star formation and galaxy formation, that require billions of years, but are at various stages of completion. Thus the universe appears very, very, old.
One explanation that I have heard for this phenomenon is that God created the universe six thousand years ago, but made it appear as if it were several billion years old. On scientific grounds, one cannot test that assertion, and it doesn't really matter if that is the case. The universe behaves exactly as if it were created several billion years ago, so we may as well assume it was, in fact, created several billion years ago. Scientifically, we will make no errors in doing so. All of our experiments and measurements will make sense under those assumptions, even if the world were "really" created last Tuesday.
When I was a Christian, I always rejected that explanation purely on theological grounds. If God created the world to appear very old when it was in fact very young that would require God to be very deceptive indeed. The universe looks old. Even though I no longer believe in the God of the Bible, I will not call God a liar.
Of course, there is Einsteinian relativity to consider, and that may be what you were referring to with your first sentence. (I can't really tell, if the truth be told.) In some reference frame somewhere, the Earth is indeed six thousand years old, and a much, much, different shape. I don't think it solves any problems for the Biblical literalist. (For one thing, it would require Noah to have died at the age of 900 million years, in a reference frame fixed on the Earth.)
Because I, and others, disagree in interpreting the evidence, that does not mean I ignore it as you assert.
Do you disagree in interpreting the evidence, or are you unaware of how to interpet the evidence? I've never seen any claim that, scientifically, the Earth appears to be very young. I have heard assertions, by literalists of Christian, Muslim, or Jewish faiths, who believe the Old Testament, that its age cannot be determined. Do you think that is the case? Have you made any attempt to find out why other people seem to think that the rocks are billions of years old, or do you not need to do so because that would simply be questioning your faith?
Those questions are mostly rhetorical, but I will ask you a non-rhetorical question related to this that I recenty asked another person who was interested in Noah's flood. If a geologist applied for a job with an oil company, for a position in which he would be expected to help them find oil, and he revealed, during the interview, that he believed in a world wide deluge that occurred a few thousand years ago, how do you think that would affect his chances of getting the job? If you think it would have an impact, why do you think that is? The last person I posed that question to declined to answer.
There are many who do find evidences of The Great Deluge. You blithely do not accept that interpretation. We disagree.
Perhaps I just haven't seen it. When I have seen arguments that make some sort of scientific claim, their claim is that such a deluge could have happened, but not that it somehow is demonstrated by the evidence itself. e.g. I read recently an argument that the crater off the Yucatan peninsula was caused by a meteoritic bombardment that occurred in the week prior to the flood, rather than 65 million years ago. However, they didn't actually present evidence that would allow one to determine which of those assertions was true. They simply claimed that the crater could be a few thousand years old, and that the Bible supports the possibility of a meteoritic bombardment prior to the flood.
I'm sure if you were to refer us to an example of such evidence we would be glad to examine it.
And, of course, once every few years someone finds the remains of a boat in northern Turkey or Iran, but it never turns out to really be a boat after all.
