Actually, article says 2000 to 3000 BCE for the palace, which would be 4000 to 5000 years old. Where the headline gets 3300 years or 1300 BCE for the wheat is not explained in the text. Although one would assume carbon dating would be effective.
1300 BCE would probably put this about a century before the purported invasion of Canaan by Joshua.
Sansom did it. c. 1000-1100 B.C.
Samson`s Flaming Foxtails throught the grainfields.
viz
Judges 15: 4-5
“Samson then went out and caught three hundred jackals. He lashed the jackals’ tails together in pairs and tied a torch between each pair of tails. He then set fire to the torches and let them loose in the Philistine fields of ripe grain. Everything burned, both stacked and standing grain, vineyards and olive orchards—everything.”
