Hi that would be at Genesis chapter 3 the failure of these two people to obey God rules and live up to moral standards as adults using authoritative responsibility. In translation of the entire ordeal, it will cause religion to be taboo on earth. It will remain a big question mark until people are given salvation from God by being obedient to all of God's Laws, 2 Thessalonians 1:8-10.
Today we have what is called religious experiments with thousands of different beliefs all trying to algin off to the same place. So, the true question is who will God pick as the Chosen ones, sons of the living God, 1 Peter 2:9-10? We have an introduction through religion by accepting Jesus Christ and building faith in him that leads towards salvation, Isaiah 49:5-6.
