Our Ancestors came to Australia, foraged for food in a rain forest where AM grew, ate the AM, and suffered the effects of muscimol hallucinations in a cave and drew paintings of a religious nature and these paintings were confirmed at 50,000 years ago, at the exact inception of religion. This was done by a species that never had religion before that. Since the species would therefore have no religious content until they ate the hallucinogens, it follows that these AM were the start of religion.
