The Israelites supposedly camped at Kadesh Barnea for 38 of their 40 years. That’s 2 million people camping at one oasis for 38 years – a city – yet not one single sign of human occupation of any kind can be found there within centuries of the time in question. Archaeologists are able to identify camp fires left by small groups of wandering nomadics in the Sinai that are hundreds of year old, but not so much as a single potsherd or bone fragment or any sign of human habitation at all where the Bible says 2 million people lived for 38 years.
There are also no signs of Israelite presence (orany other human presence) anywhere else in the Sinai at anywhere near the relevant time.
No sign of Israelite presence has ever been found in Egypt either, despite the fact that they allegedly spent 400 years there.
Many of the place names in Exodus are anachronistic and correspond to the 7th Century BCE rather than anything close to any of the proposed datings of the Exodus. These are not just different names, but places which simply did not exist at all during the time the Exodus supposedly happened.
There is likewise no evidence for the conquest of Canaan, or for any migration into Palestine from the Sinai.
The archaeological evidence all points to that distinct cultural group known as Israel arising from indigenous Canaanite groups (possibly from a loose confederation of semi-nomadic “Hapiru” tribes) around 1200 BCE.
The Exodus story in the Bible is likely inspired or influenced by the Hyksos expulsion, and the character of Moses may be loosely based on the Pharaoh Ah-Mose, but all the archaeological evidence suggests story that was constructed around the 7th Century BCE to retroject a mythic orgin and conquest history onto the Israelites.
