To give an example of science as being potentially fallable, lets look at the idea of gravity. (I'm gonna use biblical history, because it lets me give otherwise random people names and guess their intelligence levels)
At some point, Adam/Eve must have realised everything falls from their hands towards their feet. A new concept was discovered on which they could reasonably do a lot of things.
Later, they may have stood on their heads and realised things actually fell from the air to the ground. The original idea was proven wrong, but evolved. This idea held for a very long time, and is still how many people (such as most children0 understand gravity.
At some point, someone worked out there were exceptions, such as magnetism. The theory changed again, but only to allow for weird exceptions.
Relatively recently (I'm sure someone could tell me who and when) people worked out that the ground wasn't the only thing stuff fell towards. Mass actually attracted towards itself. It was merely the assumptions that there was ground everywhere and that stuff would always fall from a reasonably small distance from it that allowed the previous assumptions to work. This meant the entire idea had to be reconsidered, despite working in every situation previously encountered, to deal with physics in space.
Other exceptions discovered along the way have disproven the idea that stuff will always fall unless it is physically supported. Hydrogeen balloons allowed people to make solids 'float' due to them being lighter than air. Further ideas that it was relative weight to air that defined speed of falling have been shattered with famous bowling ball vs feather wxperiments. Finally, aerodynamics now allow lumps of heavy metal to soar through the air.
A child reacts to the idea of an aeroplane the same way Adam would have. It appears to defy everything he ever observed, destroying a law he based his life around. Many children have seen superman and tried to jump off their sofa, believing physics to have changed somehow (others just for the craic).
And now we have an incredibly complex idea of how gravity interacts with matter, often explained using a stretchy material and heavy objects making physical slopes down which objects fall, due to the effect of Adam's understanding of gravity.
I have no doubt that in 100 years time people will look back on our ideas of scientific law and theory and split them in several catagories, Nonsense, simplistic starting point and true. And if we could go there, I reckon we would be shocked to see which ideas fall where, just as Adam would be shocked to see aircraft.
