I Suspect that the traditions of the indigenous people of all counties are never forgotten and that they will always be part of their life. In some cultures, it would be disrespectful to their ancestors if certain rituals are not remembered and practiced.
I believe that what is most important for the heart and soul of humans is not just to be good and respect mankind but more importantly be held accountable for the negative energy or what some religions characterize as Sins committed against all life on the planet. We will be judged more for the "Sins" then all the good we have done. Do not hide behind the Vail of the church to commit crimes on humanity .
