In Jewish Studies, we learned about the first three plagues- Blood, Frogs, and Lice. For blood, Egyptians were not able to drink water for seven days. Which is proven to be scientificly impossible. For Frogss, frogs were everywhere, terrorizing Egyptians. Rashi said that the frogs went into the Egyptians’ bodies which is definitely
proven to be scientificly impossible. For lice, the Egyptians were attacked by little lice. Lice would make them itch when they bite. Which is proven not scientificly impossible.
I think the most difficult plague to handle was lice. I think it was Lice because the lice bit into their skin to fill up with blood. Too much blood loss would lead to death. Dum Dum Dum!
