The article ends with this:
There is no real basis for doubting the truthfulness of this historical account. It involves real people and real places.
Except that their is NO reason to believe it what so ever. No evidence at all really.
Some insist that Goliath could not have been that tall, but consider: In modern times, the tallest man documented was over 8 feet 11 inches (2.7 m) tall.
Now if anyone knows anything about the tallest man they are referring to - you would know that he would not have made a great warrior. Robert Wadllow suffered from a pituitary gland disorder, and that would not make him a mighty warrior, but a man who could hardly walk.
Also there is real disagreement to what the scripture says.
"Goliath's stature as described in various ancient manuscripts varies: the oldest manuscripts—the Dead Sea Scrolls text of Samuel, the 1st century historian Josephus, and the 4th century Septuagint manuscripts—all give his height as "four cubits and a span" (6 feet 9 inches or 2.06 metres) whereas the Masoretic Text gives this as "six cubits and a span" (9 feet 9 inches or 2.97 metres; Hebrew: שֵׁ֥שׁ אַמֹּ֖ות וָזָֽרֶת šêš ’ammōṯ wā-zāreṯ)"
Again another article asking you to believe something extraordinary without any evidence at all.
Funny the depiction below vs. what a real person would look like Goliath is really a GIANT whereas Robert is just a very tall man. Goliath seems as big as a T-Rex:)
