The Merneptah Stele (also known as the Israel Stele or Victory Stele of Merneptah) is the reverse of a large granite stele originally erected by the Ancient Egyptian king Amenhotep III, but later inscribed by Merneptah who ruled Egypt from 1213 to 1203 BC. The black granite stela primarily commemorates a victory in a campaign against the Libu and Meshwesh Libyans and their Sea People allies, but its final two lines refer to a prior military campaign in Canaan in which Merneptah states that he defeated Ashkelon, Gezer, Yanoam and Israel among others.<1> The stele was discovered in the first court of Merneptah's mortuary temple at Thebes by Flinders Petrie in 1896.<2> Petrie remarked "This stele will be better known in the world than anything else I have found" <3> and is now in the collection of the Egyptian Museum at Cairo; a fragmentary copy of the stele was also found at Karnak.<4> It stands some ten feet tall, and its text is mainly a prose report with a poetic finish, mirroring other Egyptian New Kingdom stelae of the time. The stela is dated to Year 5, 3rd month of Shemu (summer), day 3 (c.1209/1208 BC), and begins with a laudatory recital of Merneptah's achievements in battle.
The stele has gained much notoriety and fame for being the only Egyptian document generally accepted as mentioning "Isrir" or "Israel". It is also, by far, the earliest known attestation of Israel. For this reason, many scholars refer to it as the "Israel stele". This title is somewhat misleading because the stele is clearly not concerned about Israel—it mentions Israel only in passing. There is only one line about Israel: "Israel is wasted, bare of seed" or "Israel lies waste, its seed no longer exists" and very little about the region of Canaan. Israel is simply grouped together with three other defeated states in Canaan (Gezer, Yanoam and Ashkelon) in the stele. Merneptah inserts just a single stanza to the Canaanite campaigns but multiple stanzas to his defeat of the Libyans. The line referring to Merneptah's Canaanite campaign reads: Canaan is captive with all woe. Ashkelon is conquered, Gezer seized, Yanoam made nonexistent; Israel is wasted, bare of seed.<1>

This is only a reference to an 'Israel' ..... Which may have existed only as a single tribe at that time.
I would refer to more biblical archaeology here:
