It makes sense how the water turning to blood was actually a gas leak below the water, turning the water red and killing life, and how that phenomenon has happened before.
It makes sense how the frogs can survive that type of gas leak in the water but would leave the water... creating the plague of frogs.
It makes sense how lice, flies, epidemic, boils and blisters are all a result of this.
It makes sense that the volcanic eruption of Santorini is the next step of the gas leak below the water and how that is the rain of fire and ice - volcanic lava being shot up so high into the atmosphere that it hails back down.
It makes sense that locusts would be fleeing the cloud of ash from the volcano.
It makes sense that the cloud of ash creates darkness and the low poisonous gas that follows kills the first born Egyptian children because they sleep in the lowest area of their homes in a special bed and Israelite children slept on the roofs.
This movie continues to connect dots. I loved it.
