God - Devil

The people would believe anything a Pharoah said. That is just the way it went. Frogs, locusts, and the others, who knows they could of gathered them. Set some kind of a trap for them then released a couple hundred. People were very ignorant back then and believed that one small thing was part of a larger thing. Plague... Hmm... How sanitary were they back then?? Livestock dying... Shit just feed them poison or poison the food and it spreads to all of them. I doubt they had armed gaurd gaurding the food for the cows back then. Divine intervention? You think that is more feasible than poison?

Well first, it wasn't a couple hundred locusts. They completely destroyed the crops. And second, you totally skipped over the worst curse. The curse of the 1st born dying.

And yes, I think divine intervention is more feasable than the collective coloring of water, the gathering of tens of thousands of frogs, gnats, locusts, and flies, the deaths of thousands of livestock, and the deaths of many first born children all at the same time.
