What you have chosen is not a god, it is simply natural science. And it is changing every day, every minute.
I know. I was making the point by strained analogy - a homage to Einstein when he explained relativity to aetherist physicists shortly after he published it. He told them (paraphrased), "There is no such thing as the aether as you know it, there is only spacetime; if you must have an aether, you can call spacetime the new aether, but it's not at all like the aether you're used to."
(I just learned this morning that soybean oil is worse to health than saturated oil. Do you "believe" that? It is given by a significant research and has a bunch of "data").
It depends what you use it for and how you use it, what kind of saturated oil you're comparing it with (and various other factors). The public want simple soundbites of information that are easy to digest, like their oils; the real world doesn't always work like that.
Are you proud to have no certainty?
Proud? No; that's just how the world appears to be. Quantum mechanics is stochastic; you might as well ask if I am proud to have gravity.
I don't think it is a good thing. The goal of science is to "have" certainty.
No. Reality doesn't care whether you think it's a good thing or not, and the goal of science is knowledge and understanding - to explain the world we observe in terms of useful models. Certainty in science is expressed in degrees, or levels, of confidence that may get close to 100%, but never reach it (expressions of absolute certainty are generally either analytic, or shorthand for 'beyond reasonable doubt' or an uncertainty too small to consider). They are also expressed within specified contexts, bounds, or limits.
A scientific theory is a model says that, within certain bounds, our observations of the world are consistent with it behaving
as if the same rules apply in the real world as apply in our model.
Unfortunately, I don't see how is it possible to have. As a person devoted his whole life to science, I am quite disappointed.
I don't see why you're disappointed; the world is the way it is, and that's what science tries to discover.
