Natural Explanations
As noted above, some science writers and Bible researchers have suggested that the plagues were passed-down accounts of ordinary natural disasters, and not supernatural miracles. Natural explanations have been suggested for most of the phenomena:
1.
(plague 1—water turned into blood, fish died)
The redness in the Nile could have actually been pollution caused by volcanic activity, which, due to the color of Nile silt, could make the Nile turn blood red, and would also render it undrinkable. Heavy rains in the red-soiled area of Lake Victoria could have caused reddened water to wash downstream.
Alternatively, a red toxic algal bloom (red tide) could have produced large quantities of toxins that would kill fish.
Earthquakes could have caused a limnic eruption the same way it happened at Lake Nyos
(plague 2—frogs) Any blight on the water that killed fish also would have caused frogs to leave the river and, probably, die.
(plagues 3 and 4—biting insects and flies) The lack of frogs in the river would have let insect populations, normally kept in check by the frogs, increase massively.
(plagues 5 and 6— livestock disease and boils) There are biting flies in the region which transmit livestock diseases; a sudden increase in their number could spark epidemics.
(plague 7—hail) Volcanic activity not only brings with it ash, but brimstone, and also alters the weather system, occasionally producing hail. Hail could also have occurred as a completely independent natural weather event.
(plague 8—locusts) The weight of hail will destroy most crops, leaving several insects and other animals without a normal food source. The remaining crops therefore would become targeted heavily, and thus be destroyed by swarms of locusts which would otherwise be distributed rather thinly. Or the locusts could have increased due to a lack of predators. Even without these explanations, swarms of locusts are not uncommon today.
(plague 9—darkness) There could be several causes for unusual darkness: a solar eclipse, a sandstorm, volcanic ash, or simply swarms of locusts large enough to block out the sun.
(plague 10—death of the firstborn)
If the last plague indeed selectively tended to affect the firstborn, it could be due to food polluted during the time of darkness, either by locusts or by the black mold Cladosporium. When people emerged after the darkness, the firstborn would be given priority, as was usual, and would consequently be more likely to be affected by any toxin or disease carried by the food.
The word we know as "firstborn" may have meant the higher social class rather than literally the eldest sons, but the same argument applies.

I would also like to point out during the hail storms, they brought the livestock in. (I thought they were all dead)

Plagues of Exodus
Again I ask, are the Plagues of Exodus just a coincidental string of natural occurences? Or the "Wrath of an angry God"?
