Note that questioning =/= lack of trust. For instance. I remain Catholic because for every question I ask it and every answer I find it is there before me. Thus I can trust it even while I question it.
But man does the Adam and Eve problem have me confused. I am supposed to believe that at some point we had a pair of first parents that sinned. When was that? Were they the only members of the species at the time? If not what happened to everyone else? Maybe they still exist in an alternate reality, sinless and happy.
Maybe Adam and Eve weren't the only humans but they were the only ones with a rational soul and they screwed it up?
