Not new, just evolved

No one knows for sure.  Is it alien or is it human?  What does it say or mean in either case?

I haven't really heard people venture a guess as to the symbol's meaning should it be alien.  What would it mean?

I have a suggestion..  We've seen the sign before in a little different form.  The idea is from a myth. The Earth was chaos.  From the chaos came order and harmony.  Its an old, old story, and it's not Hebrew in origin, but Chinese.

Everything evolves, even alien semiology.  Their message is the same as it was from the beginning of their exploration.  If the Chinese explanation of their Yin and Yang is right, we know the meaning of the recent symbol.  If not?  Well, then all bets are off and we're back to square one.
