I know that a resonator which is the size of cell isnt in superposition unless its cooled to its ground state. My question is does this imply that my car, house even my cells and atoms arnt in superposition in nature unless some scientists decide to isolate whatever thing they want from the rest of the enviorment. The reasoning that the real world is for the most part collapsed is obviously coherent with our personal perception of it. Im honestly writing this because Im scared that if everything was in superposition my thoughts might have some effect on it. I know it seems disconected and I know that QM has nothing to do with counsciesness but there is this lingering fear that if the world is all in superposition then space and time dont exist. At that point Ive lost all sense of reality. I need to know the "whys" of why reality exists. Thank you to anyone who can help me out with this problem.
