I agree with what you are saying, but I find it interesting that physics can also predict properties of planets, stars, and galaxies interacting over cosmic distances. At that scale, you can zoom out and reduce the complexity again back to a handful of rules.
This depends on how many digits of accuracy you are looking for. With living things, we care more than with hot rocks, because the entropy gradients are so much higher.
There isn’t enough energy in the universe to calculate the full Schrödinger equation of a human. That tells us something…
