The Bible has lost its validity for people who don't actually KNOW or believe the Bible in the first place. People who are incompetent biblically find lots of errors based on their own misunderstanding of things.
Let me give you a good example. The MESHA STELE. In that document it speaks of Mesha rebelling against the "king of Israel" in the middle of the king of Israel's reign. Idiot archaeologists and Bible scholars who don't know the Bible, including the WTS, don't realize that when there was a co-rulership, the son had the same title as "king" as did the father. So during a co-rulership, there were two kings.
Now on casual reference, it looks like there's a discrepancy with the Bible because the Bible says that Mesha rebelled after Ahab died. So it looks like the Mesha Stele is saying he rebelled in the middle of Ahab's rule rather than at the end of Ahab's rule. Then people who don't know any better start to say, "See. The Bible and archaeology don't agree." But in fact, Ahab's son, Jehoram, was co-ruler with Ahab. He has two "kingship" dates. One date is in the 18th of Jehoshaphat and a second one in the second of Jehoram of Judah. But Jehoram of Judah "became king" in the 5th year of Jehoram of Israel. Meaning? Meaning that Jehoram of Israel became sole ruler over Israel in his own 6th year. That means that Ahab died in the 6th year of Jehoram of Israel. So the reference in the Mesha stele was not to Ahab the king of Israel, but to Jehoram, his son. Guess what? Guess how many years Jehoram ruled? He ruled for 12 years! So if Ahab died in the 6th year of Jehoram, that is halfway into his rule. That is, the 6th year is the middle of his rule. So the Mesha Stele is reflecting EXACTLY what the Bible is. That Ahab died in the middle of the rule of Jehoram.
So you have this WONDERFUL specific reference from a secular source reflecting precisely what the Bible says, and these stupid archaeologists and alleged Bible "scholars" don't have a clue about what is really going on.
So one of the biggest challenges when it comes to the Bible and archaeology is actually understanding precisely what the Bible is talking about. And that group is a rare group. Most misinterpret the Bible or have a loose but inaccurate understanding of the Bible and then they compare that to what is found by archaeology and seeming a discrepancy, they think the Bible is inaccurate and lost some of its credibility, when in fact, just the opposite is the case.
Now at the end of the day you still might claim the Bible just doesn't make a credible book. Fine. But a whole lot of the criticism is 100% due to bias and incompetence of those in the field. Just because someone is an expert archaeologist doesn't mean they are an expert in understanding the Bible. Thus you need the archaeologists to do their job and provide their findings, and then an expert Biblical historian to make comparisons. The problem is that archaeologists think they are competent Biblical historians and thus can make their own comparisons but they make so many mistakes it's a joke. Thus some amazing things, like the Mesha Stele, that shows the Moabites knew about the 12-year rule of Jehoram, directly supporting the Bible, is lost and in a way used to contradict the Bible.
So in the case of "archaaeology vs. the Bible" you always have to subtract the incompetence and bias of commenting archaeologists who don't know WTF they are talking about most of the time when it comes to what the Bible is actually saying. The Mesha Stele is just a fascinating example of how bad it gets.
