wow... did not expect that, lets get the understanding of basic difference between facts and theories. theory of black hole, theory of gravitation constant, theory of electro-magnetism. these are theories. Facts -Facts are observations whereas theories are the explanations to those observations based on empirical data.
example of fact- emf of a lightening strike in the unit's assigned by humans using the theory of electromagnetism is measurable, and observable. Same goes for dimensions of an object in a common understandable standardized unit these are facts.
There is no significant difference in the school of thought which makes and individual believe in supremacy of allah/god or superman or santa clause....
Now religion is not a theory- because it is not based on any empirical data that supports it's views.
Religious views are not fact either, as they are not observable based on any empirical or historical evidence and neither can be recreated in any controlled environment for statistical/experimental evaluation.
Belief - is something that doesn't need any data, any observation, any measurment, any statistics as they do not subscribe to any logic system, In religion horses fly and river part, etc. None of that has any standing in logical rationale, but then again the advantage of a "belief " is that it doesn't need to. It can simple be a personal choice. As I said I have no problem in people believing, let it be your personal stance on your perception of reality, but don't claim moral high grounds or challenge scientific data based on a belief system. Thats it
