I was reading the wiki on here about the man in black and it mentioned the statue of Taweret (the statue on the beach). I did some research on the Egyptian goddess "Taweret" and I found that she was the goddess of childbirth and fertility. This could have something to do with the fact that babies cannot be born on the island. Upon further investigation I found that she was "the demon wife of Apep". I did some research on Apep. He was an Egyptian god. Wikipedia described him as a "demon god" and "the deification of darkness and chaos". I read some more. This is a direct quote from Wikipedia.
Myths sometimes say that Apep was trapped there, because he had been the previous chief god and suffered a coup d'etat by Ra, or because he was evil and had been imprisoned.
Jacob could be something related to Ra. He is imprisoning Apep (or the Man in Black. It also could be the man in black's father, but that is for later in this blog post). Now, think back to a scene a few episodes back when the fake Locke (mib) was talking to Kate. He said, "My mother... was crazy." I thought that his mother may be Taweret, meaning that maybe his father was Apep, the demon god of darkness and chaos. Then, after much thought, I came to the conclusion that the real question in Lost was this. Is life ruled by Fate or Chaos?
