That is where scientific thought and faith diverge. Saying there are still unknowns is one thing. Science accepts that. Using unknowns as an excuse to invent an unsubstantiated series of events is simply faith. It's like the ancients not knowing why the sun moved across the sky and then inventing a bunch of gods to explain it. Believing in Apollo and being a truther are the same thing. If that's what you have faith then you are free to believe it so but don't think you can pretend it is backed by science.
No this is where you confuse what a theory is. By definition a theory is a supposition, an idea, a concept, a hypothesis. Let me give you an example, in theory if I purchase a raffle ticket I could win a prize, now as long as I don't purchase a ticket my win is theoretical, but once I purchase a ticket the win is no longer a theory, it becomes a possibility, and the more tickets I purchase the more possible and eventually probable the win becomes. Such is the case with this 911 conspiracy theory as long as their is evidence no matter how flimsy or circumstantial, it becomes a possibility and the more evidence that is gathered the more probable and possible it becomes.
