No, HERE we hit the major point of contention: you're arguing something "before recorded history," which by definition means there's no records to support it.
I'm at least providing an interpretation based on written and archaeological evidence. Yours is a leap of faith, since there's nothing in the historical record to support it. Our argument is one of science vs. religion.
And those rituals and practices originate for the same reason others do: control. Protestantism, the Enlightenment, liberalism...all reactions to that centralized control of mythology that binds society. The illiberalism of modern progressivism is the exertion of that control, on the other hand - an attempt to reconstruct/recreate societal mythology (thus the destruction of Confederate symbolism, "conservative, traditional" identity structures, even known history, and attempt to replace them with new ones.)
