It is a FACT that it fell and an hypothesis is based on that fact.
My dear, gravity is not a "hypothesis", it is a *theory*. The *theory* of gravity. Surely you know the scientific definition of a theory.
What happens if you're on the space shuttle and you drop the apple from your hand? Because it does not necessarily "fall", therefore has the "hypothesis of gravity" now been disproven? The theory of gravity, in and of itself, covers a LOT of other things other than apples falling - it also relates to time, mass, weight, etc.
But getting back to the point, you're saying that "true science" needs "facts". OK. An apple falling down is a replicable *fact*. Without getting too quantum on this, ok, sure, let's say it is. Therefore gravity is a "true science". OK.
There is a "fact" that DNA can mutate by various means. Therefore, evolution is a "true science". Yes? Is that the conclusion you're begging me to draw?
