As for "passing information" it sure has to do with ancient times, hence I wonder what might the meaning of "passing information" here? of the verb "passing"? thanks

It's a big world out there. Billions of us trying to live, love, prosper, and make sense of our brief time on this planet. Since the dawn of humanity, we've been passing information from one person to another through a common language. Unfortunately, you can't communicate with others without knowing or learning their language first.


transferring, moving, giving, conveying

Passing information might be speaking or writing, for example, or communicating in any other way.
