That word “heavens” is baffling.  We know only one sky and one space, so it is hard to say in what manner there can be many.  Because if there are many heavens, then that means there is a discrete and discernable boundary between one and another.  Meteorology has advanced to the point that it can detect pressure gradients in the atmosphere and cold and warm fronts and temperature differences, but that makes sky into amorphous flowing blobs; it doesn’t result in a countable sky.  And it only has to do with earth.    So there must be other astronomical bodies that must have their own heavens with their own characteristics.  And probably space has its own “weather” and gradients and concentrations of particles.

And God can quantify all of this!  He is the ultimate scientist.
