I got a better idea. Move Israels borders back to the original grant GOD gave them thousands of years ago, and move the trespassers out, one way or the other. POWDERMAN.
I'm not debating whether God gave them "the promised land or not"
What I am pointing out is
Historically The earliest mention of Israel as a group of people is on a 'stele' (victory tablet) of Pharoah Merneptah which dates from 1220BC. He lists the people of Israel as those he conquered during a military campaign in
Palestine. This corresponds to Exodus 1:11.
Bible Account states Joshua led the Joseph tribes in establishing a stronghold in the central highland. Later as they moved toward the coast,
they encountered Greek migrants called the Philistines. The occupation, conquest and settlement of Canaan brought both blessings and problems because the Israelite's were still living among
the highly civilized Canaanites whose religion and culture influenced many of them adversely. the Canaanite clans were - Sidon, Hittites, Jebusites, Amorites, Girgashites, Hivites, Arkites, Sinites, Arvadites, Zemarites and Hamathites. It's this conflict between the Israelite's and the
"peoples of the land" that has continued right to the present day. So who was there first? Obviously not the Israelite's . It appears the "Peoples of the land "were there first since they were encountered during the Exodus" This would include Philistines, and the Canaanite clans.
If you want to Argue God promised them the land through a covenant with Abraham , that is a separate Biblical debate.
