So the thing is, like other commenters have said, you’re asking metaphysics things through the prism of science, which does not work because by nature, science uses the (mostly) objective scientific method, while metaphysics is based on subjective assessments.
You have to separate the physical, material universe as being in the domain of what can be known, from the rest, which can not be, and never will. This does not mean it doesn’t exist, just that it can never be studied or proved in any way, so anyone can believe what they wish about it without leaving rationality (as long as the belief does not imply things concerning the material universe)
