That Wiki article is correct, Israeli Archaeologists were sent to find proof of of Israel and the Exodus story, they honestly and correctly reported back they could find No Evidence for it !
And as the Article hints at, Israel as a group comes much later in history than the Patriarchs and the Moses stories are set. The "History" we read in the Bible was invented by returnees after the Babylonian exile to give a boost to Nationhood for those that now occupied the land, they wanted a narrative about their history as a Nation that would justify their position. That same narrative is being falsely used by Israel today, and falsely believed by gullible and ignorant politicians in the Unite States and elsewhere. The whole Bible is really 90% or more a work of Fiction.
This explains a lot !
