Exactly — which strongly indicates that there was some sort of “driver” — some force that caused those things to fall into those narrow windows. Planck’s Constant is one such thing. The slightest deviation and life as we know it could not exist.
It would be a different Universe, with different laws of physics and different life. That life would look around and conclude that their set of constants is the only one that supports life as they know it.
Another way to think about that might be:
Since the slightest deviation would preclude life as we know it, perhaps there is another universe in which the constant of proportionality relating the energy of a photon to the frequency of that photon (also known as ɛɜɝɞɟɠɣɥɧɮɳɷʂʄʱ in that hypothetical universe). is sufficiently different that we could not live there.
However, intelligent life does exist there and has advanced to the point they have deduced the principles of Quantum Mechanics, and have determined the value of ɛɜɝɞɟɠɣɥɧɮɳɷʂʄʱ with utmost precision. Perhaps they are speculating on the remarkable tides of fate that have placed ɛɜɝɞɟɠɣɥɧɮɳɷʂʄʱ in the remarkably narrow range that allows life as they know it to exist.
Perhaps no "narrow range" exists and life was designed to suit the existing conditions? Perhaps intelligent design applies to more than one universe?
Have you ever wondered why our eyes are most sensitive to "visible light" which is the same portion of the electromagnetic spectrum that carries the lion's share of the Sun's energy output. Amazing coincidence, don't you think?
