I have joined speech and debate at my school and I need a to know some cultures that predict the arrival of the indigo children. Well I know the Mayan calender "predicts" a change on Earth in 2012 because it ends there, and I know there are some indigo cultures that have a prophecy towards them but I can never find exactly what culture and how they predict it... so does anybody know? (please no answers saying, "indigo children don't exist" thank you)
