Levers are levers. Simple machines are simple machines. Complex machines are little more than combinations of levers and other simple tools and machines. Religion is religion. Beliefs are beliefs.
Bodies are bodies.
Our legal systems are based on legal systems milleniums of years old. Histories are compilations of limited perspectives of the authors and those interviewed. Wheels, pyramids and spaceships were all possible, all eventful, and all occured in their own time. Healing a personal hurt, a small cut or brain surgery were all possible, all eventful and all occured in their own time. None or all will be equally blaize or astounding millenium from now.
