Egypt’s chariots were all destroyed at the time of the Exodus.
Only Chariots produced after the Exodus would be found by archaeologists.
No discoveries horse drawn chariots have been found prior to the 15th dynasty. This would tend to suggest that the Exodus took place before the 15th dynasty. One would not expect to find chariots of dynasties prior to the Exodus because they were all destroyed at the time of the Exodus.
Wyatt found chariot wheels covered with coral strewn across the bottom of the Red Sea. There was a well preserved golden 4 spoked chariot wheel. He also found six and eight spoked chariot wheels covered with coral from one side of the Red Sea to the other in the Gulf of Aqaba where there is a large beach and a natural land bridge at the opening of the Wadi Wadir, just a little bit north of Jabel Lawz on the opposite side. Wyatt also found a pair of columns which appeared to have been left by Solomon to mark the site of the Red Sea crossing at this point.
Unfortunately, as no examples of 12th dynasty chariots have been found, the chariot wheels found by Wyatt were dated to the 18th dynasty. This has lead many an archaeologist to go looking for the Exodus in the 18th dynasty. There is no evidence for a mass Exodus in the 18th dynasty. There was an exodus at the end of the second intermediate period but this is when the Hyksos kings were evicted from Egypt and is clearly not the Israelite exodus.
The Bible states that the exodus pharaoh pursued the Israelites with all of Egypt’s chariots and that these were lost in the Red Sea. One would, therefore, not expect to find a chariot that predated the exodus. If a chariot has been found, other than in the Red Sea, then it must have been produced after the Exodus.
While the Hyksos (15th dynasty) did use chariots to invade and occupy lower Egypt, they were only able to do this because the Egyptian army had been decimated by the Exodus and all of it’s chariots were at the bottom of the Red Sea.
Many historians and archaeologists believe that the horse drawn chariot was introduced to Egypt by the Hyksos because there are no findings of 12th and 13th dynasty chariots. If all of Egypt’s chariots were lost at the time of the exodus, the finding of 15th dynasty chariots should suggest that the Exodus occurred prior to the 15th dynasty, namely the 13th dynasty. It also follows that the chariot wheels found in the Red Sea by Wyatt were from the 12th and 13th dynasties.
The Hyksos were credited with having introduced the chariot to Egypt only because no 12th and 13th dynasty chariots have been found. The fact that Hyksos chariots are the earliest surviving chariots to have been found means that the exodus took place immediately before the Hyksos entered Egypt. This would further support a 13th dynasty Exodus.
Also supporting a 13th dynasty exodus is the prolific use of mudbricks in the 12th dynasty and the finding of a slave village at Kahun that was rapidly evacuated in the 13th dynasty when Neferhotep I was ruling (as evidenced by scarabs found by Petrie). Amenemhet III has the credentials to be the pharaoh of Moses birth and the pharaoh that Moses fled from. Sobeknefru has the credentials to be Moses foster mother and Amenemhet IV has the credentials to be Moses himself!
