Tribalism is completely illogical and only exists because early humans were extremely stupid and then the next generation gets brainwashed as children.
How interesting an opinion, except you can exhibit tribalism in many animals, however no animals display signs of religion. One is a natural phenomenon designed to keep our species safe, the other is a tool designed to keep the peasants fearful and under control.
I'm sorry that telling you believing in magic and sky wizards is silly, how ridiculous of me.
