Why do all cultures have naming ceremonies?

One should not answer this question for all cultures however, it is a very good question that should be answered.

My people had only two names before first contact, we now have three and maybe more depending the culture around us.

First we were names early in life to make it easy for mother, father, relations and the tribe to get our attention, as soon as the elders were convinced that we wanted a quiet time to speak with Creator, an elder, the spiritual leader and the person to be named would go to Creator in prayer.

The only reason for this was to make it that much easier for that person to block out the world and just communicate with Creator.

Creator used this name as the full tribal name for open talk!
