I am happy! It did not take too much. About 3 minutes.
In any way it connects nice to what you are trying to communicate.
You may find it surprising but the word hu-man in Greek is "anthropos"
wich has two synthetics "an" from "ano" and "thropos" from "throsko". Both of them are Greek again with deeper meaning and origin flawlesly
connecting to the rest of language. Anyway these two synthetics mean the one who is looking up.
I guess this one you did not expect right?
There was a post of mine-many many many-posts ago that explained this in more detail but i guess you got it even in this minimal explanation.
Take earth of the equation for a moment and then ask yourself which way is up.. does it even exist?
Say you are standing in space, the only other exist we collectively know of if Earth was not here. If we went in the opposite direction of our feet,
we might consider that up. Until you go "up" then turn around.. now which way is up?
