Here's something that came to me after the 7th episode (Ep: 3x7, Not in Portland
). The island is actually the center of the earth that was discovered somehow. The island is the original piece of earth before it separated. It's where we evolved from...the statue with 4 toes...before civilization corrupted things. The concept of fate is human behavior maybe? The numbers, perhaps the first numbers perceived by humans at that time. The smoke monster, I've no idea.
