It wouldn't look like natural processes spanning millions of years, which is what we do see. That is, unless, you want to argue that God changed the evidence to deceive us.
Why do you care what a Force you do not believe in can or cannot do?
Could God shuffle the deck of layers and lay it back down however He wished? Why not. Could He have messed with decay rates to obscure or confuse our ability to accurately date? why not.
Am certain God could make it look a rainbow layered cake that is billions of years old if He wished. Given what Christians believe concerning God, am not sure why we should think Him incapable of covering His tracks if He wanted to or even at same time tossing the salad and fixing the isotopes to make everything appear far older than it others would have (not saying He did all that but that He certainly could - and the idea works with expounding on what "erase" or "wipe away" could mean). Have already addressed possible motives for doing so.
What you need is evidence that a supernatural flood did happen.
That's the rub here. Am not the one here who is in need of anything.
Yeah, there is. If you want this supernatural force to be included in an explanation of the geologic record then you need to demonstrate that it exists.
Happy to do so elsewhere, but not in this thread as technically it is not even allowed to question His existence here. Besides the OP clearly asks Christians, which sort of further ties our hands if we want to be curtious and also play by the rules. There are areas in CF where one could go and challenge Christians to defend God existence, but this section is not that one.
If the only reason you believe a flood exists is because of the Bible, then that is a tacit admission that there is no evidence for a recent global flood in the real world.
Wouldn't call that tacit anything. Again, see page two for no evidence of naturally occurring flood, followed by repeatedly pointing out the event in question was not a natural one.
I stated two pages into this thread and repeated several times now, it is not possible to state there is no evidence of a Supernatural event because we have no guidebook for what that evidence might look like today, we have no clue what else besides covering with water was done to the earth. The idea a supernatural Force, God, could cover the earth with water yet be unable to arrange matter in bulk at will has no support at all.
Lacking that guidance of what or how anything else may have been doe, the best we can do is say we see no evidence of a naturally occurring global flood. The truth of that statement was clearly stated by me on second page of this thread and also repeated several times since. That truth cannot exclude the possibility of one, some, most or even all the older rocks layers could have origin in and the result of a single supernatural event. Which means, because we lack any guide on how that was done, we would not be able to understand what we are looking at now. And yes we should think He could arrange it took look like multiple events spanning billions of years if He wanted to.
The Young earth (YEC) Creationist still believing in a Noah flood would want to argue God did the extreme mentioned above, jumbling all the layers in way that makes the earth look much older to us now. And as Christians do accept more and more older earth from that YEC view, starting with over 10K years ago, God producing a global flood would need to do less and less to obscure the age of the earth while also obscuring the evidence of a single global catastrophic supernatural event. I have always favored a view that says the earth is far older than the YE crowd would have it. But even in my view, the evidence from this global event has been obviously obscured in some manner so it is not evident at all to us right now except to say we know at one time or another it appears every part of the planet had water over it.
So it is not a matter of lack of evidence for a Supernatural event, it is a matter of not being able to see it if it was staring us in the face and waving its arms at us.
