The Ten Plagues of Egypt
Exodus 7-12 recounts ten plagues — water to blood, frogs, gnats, flies, livestock pestilence, boils, hail, locusts, darkness, and the death of the firstborn — by which the God of Israel compels Pharaoh to free the Hebrews. Some scholars propose a natural "ecological cascade" (a red Nile bloom triggering a chain of frogs, insects, and disease) or a Santorini/Thera eruption for the later plagues; others read the narrative chiefly as theology — a deliberate polemic showing Yahweh's supremacy over Egypt's gods. No Egyptian record corroborates the events. Partial natural cascades are plausible for several plagues, but the full sequence as told, and its historicity, remain genuinely uncertain.
