I don't know how the age of the earth being 6000 years old could be considered a 'settled science' when it isn't a scientific conclusion at all, but a religious one. The conclusion that the earth is the center of the universe is based on the exact subjective experience that modern science now tries to avoid. Alchemy is certainly not scientific due to its inclusion of Hermetic principles. Heavier objects falling faster than light ones is a perfect example of how subjective human experience is ill equipped to describe the world around us. Even now many people think that light objects fall faster than heavier ones (I even had to explain this to a group of college educated friends - to my dismay) as that seems to be common sense. Unfortunately the way our minds perceive the world is often not how the world works at all. Common sensical things that add up perfectly in your head (e.g. god caused event x to happen) do not actually translate into the real world. These blips in human rationality are things that modern science attempts to circumvent through repetition, falsifiability and error thresholds.
Nevertheless, you are correct in saying that science has often been wrong over the years. It is of course, a learning process. However, that still doesn't mean that it is inherently superior as a way of describing and explaining our world than subjective human experience. With regards to the basic workings of our universe, we actually have that pretty much down. Quantum mechanics has made successful predictions down to an error of under 0.0000000001%. Prof Michio Kaku once said “It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct.”. Most new theories these days are actually just tweaks and corrections to existing theories. Einsteins theory of relativity may have superseded Newtons laws of motions, however that does not mean the Newtons laws are wrong, they are still taught up to undergraduate level, it's just that have new models that are more accurate.
Finally, I deplore the idea that scientists are close minded to all the possibilities out there. Scientists have shown time and time again that they are some of the most open people when it comes to the world around us. Science requires an imagination in order to contemplate new theories. It's taken scientists to show the world that time and space are the same thing, that when you look into the distance you are peering back into time, that we are 99% empty space, that we are biologically related to monkeys, that matter can be waves and particles at the same time, that we are made of materials that were forged in exploding stars. It's poetic. You literally could not make this stuff up. I, and multitudes of other scientists out there are open to any multitude of possibilities (including one of a supreme being, or of a spiritual world - after all, the theory of a multiverse has been posited, why couldn't one of them be a universe of spirits). We just have one teensy weensy requirement, show us some suitable evidence for it so we can take you seriously.
