When did waving to others to say hello or goodbye first enter the historical record as part of a culturally accepted form of human interaction?

This question appears to be off-topic. The users who voted to close gave this specific reason:
- "Questions on social sciences other than History are off-topic here, unless they also involve history in some fashion. While ethics, archaeology, etc. are all connected to history, each field has their own experts who are better equipped to answer such questions." – Semaphore, Mark C. Wallace, Gwen, Steven Drennon
I believe it came about before advanced human civilization. The waving of a hand is to get somebody's attention in the most effective and conservative way possible. Waving a hand can attract one's attention but at the same time is not overly conspicuous. This could have helped early civilizations when hunting or during warfare.
