blah, blah, blah....Isn’t anyway to prove it...
No way to disprove it either.
Actually, no. What if the wood is dated at 4800-5000 yr old? If it is not the Ark and is a fraud, it’s a fraud built many hundreds of years ago, as there is no record of its construction. So, how would someone (actually many people) find enough wood all dated the same at several thousand years old, where they have no way to date the wood they find? If all the wood dates as being 5000 yr old, there would be no way to explain its construction unless it was built 5000 yr ago. If it was built 5000yr ago, there is no way to explain what it’s doing at the 13000’ level on the side of a mountain.
So, if the wood all dates as being this old.....
There is no way to "prove" any event from history. The historical method does not lend itself to "proof." "Proof" requires a controlled experiment that is repeatable in laboratory conditions. However, it is possible to provide enough evidence that all but the most recalcitrant skeptic must accept the findings.
For example, the explorers could take photos that are timestamped and gps'd. The explorers could take others up to the same location who could verify what was found. There is much evidence that could be put forward that the explorers have yet to provide. I am skeptical of this too. However, I am open to being convinced if enough evidence is put forward. I suggest a similar openness on your part.
