I can see that this is a topic that is bound to run around in circles with people trying to defend either fate or science and then someone coming behind them disproving it. The fact is that what is real depends solely on the perspective of the individual person. Nothing is absolutely provable, so we just have to decide what we want to believe is real or not.
I like using the example of sight for differing views about things. What if my eyes actually made the world around me inverse colors than what everybody sees? How would anybody know? I couldn't wrongly say that something looks dark when it really looks light because I had been taught that what other perceive as light is called light and what others perceive as dark is dark. The only way that anybody would be able to know if my sight perception in inverted would be if somebody went inside my head and saw through my eyes. But just because I see a different way doesn't make it wrong. It is simply how I perceive the world, and others will probably come up with different ideas than mine because they see the world different than the way that I see it. There is no way for us to absolutely prove anything to each other, but we can convince each other to change our minds even without absolute proof. We could even opt to argue till we turn blue in the face, but the argument will still lack absolute truths because of the fact that we perceive the world differently.
It sounds like to me that people are hiding behind both fate and science in this discussion by simply stating "because it is so." I admit that I hide behind fate, but I also recognize that this discussion will prove no absolute truths for anyone. We can try to convince each other of our ideas, but there can not be any absolute answer that comes from this discussion.
I just wanted to go ahead and state that for the benifit of anyone who adds to this discussion hoping that someone will present them with an absolute truth or affirm that their idea is an absolute truth. Sorry if I lost anybody.
