In the movie, most members of our society still has idea of over a hundred if not a thousand gods. But religion is such a controversial topic that is why a lot of producers veer away from making this type of movie.
In the movie, Moses went to a Mount Sinai cave to literally chisel the Ten Commandments on tablets of stone. I think that is more realistic than having lightning bolts carve the 10 commandments as depicted in other movies.
We, humans, are judgmental beings, and we judge fast.
Sometimes, human as we are, we tend to add or sometimes omit a sentence or two resulting to a confused collection of impression thus leading to a tale or, hell yeah, tales from the dragons.
If you are really good inside and out, then don’t believe on painted impressions cast by devils against other human beings. Always be good no matter what.
