You don’t have any idea what you’re talking about. The spears weren’t carbon dated, in addition, a worldwide flood wouldn’t do anything to carbon dates.
To the ‘guy’ that says I’m full of sh*t, First off, if they weren’t carbon dated, how did they know how old these spears were? Because they may have been imbeded in coal? Does anyone remember the incident where coal miners broke into an air pocket in the coal and there was a frog hibernating inside that slowly came alive!? Second, If you aren’t A Christian or Jewish person, you won’t understand the concept of the ‘canopy’ of water and mist surrounding the earth before the great flood (the great flood was written about by almost all civilizations living at the time), thus keeping the sun’s more harmfull rays from man, allowing him to live to great ages. It also preserved a delicate balance of things we will never know about. When the flood came (canopy dropped and the oceans within the earth were released) It threw ‘carbon’ dating out the window. The instant bombardment to the earth of these harmfull rays affected mankind by greatly reducing their life expectancy, the rays also radiated and fried the earth’s fauna and substances of every kind as to render any type of carbon dating unreliable. AFTER the flood carbon dating became spot on and reliable. I may not be totally correct about all of this and laugh if you want, but that’s where faith comes in. We will find out who was more accurate about these events when we get to heaven.
