Well, here is a scientist:
Science, since people must do it, is a socially embedded activity. It progresses by hunch, vision, and intuition. Much of its change through time does not record a closer approach to absolute truth, but the alteration of cultural contexts that influence it so strongly. Facts are not pure and unsullied bits of information; culture also influences what we see and how we see it. Theories, moreover, are not inexorable inductions from facts. The most creative theories are often imaginative visions imposed upon facts; the source of imagination is also strongly cultural. [Stephen Jay Gould, introduction to "The Mismeasure of Man," 1981]
I have no problem with this nore does it change the point I made.
Hunches, intuition, imagination,... they certainly are factors in how people come up with ideas as potential solutions or answers to certain problems or questions.
But before you can imagine a solution to a problem, you need to have a problem. And the better you understand the problem, the more successfull you'll potentially be at coming up with a solution.
So while solutions (like relativity, evolution, germs, atoms, etc) are not simply inductions from the facts, they most certainly are inspired by it. Because you are trying to come up with a solution to a
specific problem or question.
Evolution was imagined as an answer to why there was diversity of life and observations thereof.
Whereas continental drift, which eventually became plate tectonics, was a solution imagined as an explanation for the shape of continents and how they seemed to "fit together" like pieces of a puzzle.
Why this doesn't change the point I made, is simply because of the nature of scientific inquiry.
See, when scientists come up with these ideas, through whatever means, they don't just leave it at that and go with the first thing they imagine and assume it to be accurate. No... Instead, they test their idea to determine its accuracy.
While this doesn't happen with religions ideas. In fact, the supernatural core of most religions even make it impossible to test it.
So the point remains: through observations of nature and the formulation of potential explanations (through whatever means) and subsequent testing of those ideas, we'll eventually again develop understanding and knowledge that was lost before. We'ld rediscover the relation between gravity, speed and time. We'ld rediscover radiation, electro-magnetism, the laws of motion as it applies in classical, the weirdness of quantum physics, chemistry, germs, evolution, etc etc etc.
We'll have different words for it. We might even develop a different type of math to describe it. But the underlying processes, facts and phenomenon would remain the exact same.
Not so with religion. New creation myths will be invented. New cataclysms will be invented. Brand new lore of how it came to pass.
