And we made levers before we cracked open bodies to see how joints work, but it is still on the same principle. You intentionally missed the point. Figures.
Still on the same principle?! The same principle as the reverse engineering of nature that you claimed?!
Nonsense! Levers were not reverse engineered from nature.
Moreover, levers have nothing to do with either math, creationalism, or even evolution.
You've gotten yourself off-topic.
