Ha, I love your ignorance. Even the jews don't believe there was widespread egyptian slavery http://www.haaretz.com/jewish/the-jewish-thinker/were-jews-ever-really-slaves-in-egypt-or-is-passover-a-myth-1.420844
Ite, missa est.
The reality is that there is no evidence whatsoever that the Jews were ever enslaved in Egypt. Yes, there's the story contained within the bible itself, but that's not a remotely historically admissible source. I'm talking about real proof; archeological evidence, state records and primary sources. Of these, nothing exists.
It is hard to believe that 600,000 families (which would mean about two million people) crossed the entire Sinai without leaving one shard of pottery (the archeologist's best friend) with Hebrew writing on it. It is remarkable that Egyptian records make no mention of the sudden migration of what would have been nearly a quarter of their population, nor has any evidence been found for any of the expected effects of such an exodus; such as economic downturn or labor shortages. Furthermore, there is no evidence in Israel that shows a sudden influx of people from another culture at that time. No rapid departure from traditional pottery has been seen, no record or story of a surge in population.
To be correct, not all firstborn were babies..
And not all were human.
Egyptians were keeping the Israeli people as slaves
