As I mention, I view it as a possibility, not as the final answer. Because if we accept it as a final answer, then we won't be any different from those who reject TOE. Once we accept something as final, it would be very difficult to change our thinking even if someone else proved it false.

Also, another thing I would like to mention is, I believe evolution happen, and this happen is beyond doubt. However, the question that arise is, does macro evolution happen (as Darwin's TOE suggested)? Or only micro evolution have occurred?

"I hate to say this but it's due in part of religion. Religion was opposed to the idea of the earth revolving around the sun. It took several hundred years and several near-deaths of prominent scientists but eventually we reached the point where it is no longer debatable (ie we built telescopes and went into space).
"
That's why I mean, until it can reach a point where it is no longer debatable, there exist other possibilities, no?
