The original religion. Prior to Adam and Eve exchanging life with God for death (Romans 1:23) they had direct access to God (Genesis 3:8). After separating themselves from God in an event now called Original Sin, their religion would’ve been more limited. Immediately after their departure there are some clues that they maintain a connection to God, for example Cain and Able offer sacrifices to God (Genesis 4:4-5).
Our residual awareness that there is a greater power out there, a deeper meaning to reality (Romans 1:20) and something to measure morality by are what you could call residual clues of that original religion.
