Perhaps the biggest problem with migration is a failure to integrate. Abraham and his Sumerian clan didn't integrate with the Canaanites and once the Elamite invasion had become a distant memory, this lack of interbreeding was a source of division. It didn't help that Abraham and clan, having delivered the Canaanites from the Elamites thought themselves superior culturally. It was similar in Egypt but the boot was on the other foot.
Joseph and his brothers were put in charge of livestock as their experience was above that of the Egyptians at the time. They flourished and became very wealthy but they didn't mix with the Egyptians and became a culture within a culture. For generations the descendants of Abraham became more powerful and their numbers swelled. Times change though and so do Pharaohs. Historical accounts tell us Canaanites first appeared in Egypt towards the end of the 12th Dynasty (1800 BC), and by 1720 BC had established an independent realm in the eastern Nile Delta. Whether these were references to Abraham's descendants is unclear but their power began to wane during the 13th and 14th Dynasties, most likely due to famine and plague.
In about 1650 BC, both dynasties were invaded by the Hyksos, who formed the Fifteenth Dynasty. The Hyksos were rulers from foreign lands and their arrival coincided with the Santorini eruption, suggesting these rulers were of Aegean origin. The penultimate ruler of the Hyksos dynasty was Apepi / Apophis / Epaphus, son of Io who fled Mycenae for Egypt (see Redefining Atlantis). The Pharaoh Ahmose waged war against the Hyksos and expelled Khamudi, their last king, from Egypt around 1550 BC*.
With the departure of the Hyksos kings, the influence of Abraham's descendants dropped like a stone. They were many in number and successive Pharaohs saw them as a threat, in a short space of time they became mere slaves. One Pharaoh (I believe it to be Thutmose I) ordered the death of newborn boys from the 'Canaanite' population in order to keep their numbers down. there are conflicting dates for Thutmose I's reign with some sources giving it as 1526-13 BC, whilst others give 1506-1493 BC. Either would fit in as being around the time of the birth of Moses.
The story of how Moses was saved and grew up within the Egyptian royal household, is well documented so I see little point going over it here. Moses becomes an interest some 50 years later.
When talking of 'deception' there is an obvious negative connotation but it doesn't necessarily mean the perpetrator has ill-will. In the case of Moses there is no doubt he acted to save his people from slavery but there is also no doubt he pulled off the biggest and best deception of them all. To be fair, he was assisted in no small part by Mother Nature.
Now I'm not interested in the Burning Bush, 10 Commandments, and all that. My interest is in cold hard facts. Whether Moses had any interaction with a deity or possibly extra-terrestrial is really no concern. It is the interaction between Moses and the Pharaoh that intrigues me. The eruption of Santorini in 1650 BC paved the way for the Hyksos kings and now it would set the children of Israel free.
Archaeological evidence on Crete (halfway between Santorini and Egypt) tells us there was a tsunami in 1450 BC and 30 years ago this was the date given for the Santorini eruption. However, in the last 10 years or so this date seems to be revised to 1650 BC and 1450 BC has seemingly been forgotten. What prompted this revision is unknown to me but having to take the word of experts, I needed to find an explanation. The thing that eventually came to me was as a result of studying other volcanoes and their behaviour.
In the absence of an eruption it is my belief the 1450 BC event was a cone collapse triggered by an earthquake. The magma ebbed back after the 1650 BC eruption leaving Santorini (Atlantis) sitting on top of a hollow chamber. It may not even have needed an earthquake to cause the collapse, it may just have been a matter of time i.e. 200 years. This event in the Aegean was crucial to what was going on in Egypt. It was instrumental in the 10 plagues legend and Moses took full advantage. Incidentally, Rabbinical Judaism calculated a lifespan of Moses corresponding to 1391–1271 BC; Jerome gives 1592 BC, and James Ussher 1571 BC as his birth year. They're all wrong, his date of birth was between 1520 and 1505 BC.
Moses convinced the Pharaoh that the series of disasters were attributable to the wrath of his God. If we analyse the story, the Pharaoh wasn't fooled immediately but the persistence of Moses and the seemingly endless number of disasters eventually convinced him..... or did it? Apparently the Pharaoh allowed the children of Israel to leave then changed his mind. I think it just as likely he never assented at all and pursued the Israelites when they made off during the confusion.
The Ten Plagues
2. Frogs - The cause of the rivers turning red is due to algae and this may well have caused a freak number of frogs to spawn with a food source in plentiful supply. This is again a by-product of drought and not due to Santorini.
3. Lice - As livestock died flies, gnats, and lice would also be on the increase.
5. Diseased Livestock - Drought and famine induced no doubt, still not impressed.
6. Boils - Even at this point there is nothing to suggest divine intervention and everything happens in a natural progression, triggered by the initial drought.
7. Thunder and Hailstorms - This is a phenomenon commonly associated with volcanic eruptions but there is no definitive time-span for these plagues so although it could be due to Santorini, it doesn't necessarily have to be.
8. Locusts - Although Egypt was having a pretty torrid time of it, so too were all the eastern Mediterranean peoples. A plague of locusts is still not rare enough to be considered the wrath of God.
9. Darkness for 3 Days - This is directly associated with volcanic eruptions and can have no other explanation. The volcanic ash from an eruption or even dust plumes from a cone collapse would darken the skies as it passed over Egypt.
10. Death of Firstborn - This seems pretty selective and of all the plagues it is the one I would question on the literal meaning. The associated volcanic ash / dust would possibly be enough to kill infants if it found its way into their lungs but would not harm an older child or adult. Was the plague referring to 'newborn' rather than 'first-born'?
The flight from Egypt was another piece of good-timing. The parting of the Red Sea was - as is now widely accepted - a reference to the Reed Sea or Sea of Reeds. This is an area of marsh on the north coast of Egypt. The waters parting were actually the sea withdrawing as it commonly does with a tsunami. This would have made the marsh passable on foot. The Egyptians saw the Israelites escaping and gave chase when the wave of the tsunami struck.
With such an amazing run of luck, perhaps it was divine intervention....... nah, Moses just got lucky, and big style.
*In Mycenae a gold face mask was unearthed and wrongly named the Mask of Agamemnon. This mask was actually the Mask of Epaphus (Apophis). It is dated to 1550 BC (Agamemnon didn't appear until 300 years later) the time the Hyksos left Egypt. The body of Epaphus was returned to his native Mycenae for burial. I cannot verify this of course but one day the historians will stop scratching their heads and finally work it out. I told them where Atlantis was 30 years ago and only now are they starting to acknowledge I was right.
