I am quite skeptical that it was the fireworks for the Exodus . . .
Sometimes God uses natural phenomena and features. Sometimes He doesn't. I think the Exodus was super special to Him and that much of the time, He used other than natural stuff.
imho, of course.
I'm not the least bit impressed with the Nat Geo special on the topic.
I was taught that the miracles all have scientific explanations. The miracle wasn't the events themselves, but that they occurred at the exact right time to be useful. You're free to agree or disagree.
I think that either way (volcano or no), the events of the exodus was a supernatural event. The specific details do not to me make a difference in seeing God's in it. But I just don't see that the dates match. 1600 BC for the Santorini eruption is earlier than most dates I've seen for the exodus.
