This article posits that there are scientific explanations for all of the miracles attributed to the story of the Exodus; saying for example that the ten (or three depending on whom you believe) plagues were caused by a chain of events starting with a bacterial outbreak in the Nile that turned the water red, killed the frog eating fish, causing an outburst of frogs who were then poisoned by the dirty water, causing an outbreak of flies, causing all sorts of other diseases to spread, etc. Thus, the most miraculous thing about the miracles Moses are not the miracles themselves, but their timing.

There are a few ways to go with this:

#1: All folk takes are given to exaggeration, hyperbole, and flat out invention. This is to make thinks more exciting and magical. The waters didn't part. Why does everything have to be so damn literal?

#2 I liked what Stephen Hawking has to say about religious belief: it's true that we lack the tool right now to get past the question of whether there was a supreme creator or design to the universe, however, the universe appears to operate according to set physical principles that do not change. The intervention of a supreme being at any point after creation would alter these physical principles and thus it seems logical that if there is any higher power this higher power is a watchmaker and nothing more.

#3 Number two, said, however, part of the delight of art is to create frameworks through which we can focus our creative outlets. Think of a sonnet, or a fugue, or a flatfoot dance. These are ways of expressing oneself but with parameters and the best measure of art is the degree to which it can do the astounding within boundaries that the audience can comprehend. In this regard, infecting a river with bacteria, knowing full well that it would lead to a chain of events that would end with the exodus of the Jews from Egypt would qualify as a sublime work of art on the part of a creator; causing events to occur within the narrow boundaries of physics already established at creation.

#4 I, personally however, refuse to believe in any deity that would create whole civilizations of people simply to destroy them or to make them suffer (e.g., Egyptians, or Amalekites) or cause them to live and die for hundreds upon hundreds of generations without knowing of said deity and therefore having no option but to burn in Hell at the end of their lives (e.g., every person that never even heard of Christianity). I also refuse to believe in any deity that advocates genocide and also just basically makes people feel shitty about themselves.

#5 For these reasons and many more (despite the delicious food and the overall sense of nostalgia for my childhood) I absolutely repudiate Passover. I do not believe its message is about freedom in the greater universal sense so much as it is about freedom in the particular sense: freedom for us and everyone else can go fuck themselves; as long as we have what we want it doesn't matter what you have. It's been 4000 years and I think maybe it's time to change the message, don't you?
