No, it doesn't.
Archaeologists have recently found a shard of pottery with the name "Goliath" inscribed on it.
The shard dates back to around 950 B.C., within 70 years of when biblical chronology asserts David squared off against Goliath, making it the oldest Philistine inscription ever found, the archaeologists said.
So does that lend any significance to the historical account in the Bible? Let me get my shoehorn out here. Urrrgghh, that data is hard to force in there!
No. While the finding is incredible, it proves exactly dick when it comes to Biblical chronology.
While the discovery is not definitive evidence of Goliath's existence, it does support the Bible's depiction of life at the time the battle was supposed to have occurred, said Dr. Aren Maeir, a professor at Bar-Ilan University and director of the excavation.
No. It proves that the name "Goliath" goes back to 950 B.C. That's all. Reading anything else into the finding is shoehorning it in to what you want to believe. It's just not intellectually honest.
