With the exception of two or three posters so far no one, other then the poster, bothered to check science.
This is the 21st century and our understanding of what the land has told us reveals:
1. Abraham... if he ever existed he never met a Philistine...
2. Joseph. Based on earlier stories but not histoircal.
3. Exodus. Never happened. Oh many priests from Egypt moved north in Shishaks time etc... but no mass exodus.
4. Conquest. Not really. As already stated... more a rebellion within Canaan.
5. Israel's first king was likely Egyptian.
