I have a feeling they won't address the point, either.
Judges 20:16 Among all this people there were seven hundred chosen men lefthanded; every one could sling stones at an hair breadth, and not miss.
The fact is, they were rendered useless as warriors when they saw the size and might of this guy; and David showed up and used his faith in the LORD to override reality and get the job done.
I'm planning on starting another thread later along the same line, using the twelve spies who spied out the Promised Land.
Israel's decision to go with science over faith is what cost them 40 years in the wilderness until that generation died out.
In fact, after God placed the Promised Land off-limits for the next forty years, they went ahead and tried to enter it anyway on their own, and God simply withdrew His protection and science did the rest.
