Further definition: In this Immortal World, one is born into this world we know as Earth, just as humans are today. The only difference being we never die. But for population explosion reasons, let's say we have the option to move - to another planet, another dimension, whatever. But we can still come back here and we can still easily communicate with others on Earth. Internet of the Cosmos? Sure. Why not.
Information then would be gained more first person than through word of mouth or ancient writings, something we have no way of verifying factually now.
In the realm of religion and faith, any and all questions we may have about the holy books - "Did Moses really part the Red Sea?" "Was the Qur'an really revealed to the Prophet, Muhammed, or did something else really happen?" "Did God really give the Ten Commandments and the Torah to Israel, or was there some stretching of the truth there?" "Excuse me, Jesus, with all you said, did you really never write a thing?" can be answered first person. Then it's up to us to decide how much we want to believe. At least we wouldn't have to hear (like I did), "Don't question your faith."
In this respect, in the being able to ask eye witnesses what actually happened that fateful day, we could better answer the questions that have been asked for many a millenia.
Not being able to get scientific proof to the answers I sought, and simply being told, "Just have faith", is why I began to lose faith in the Catholic teachings. And that was long before the priest crisis. My mind could not accept someone telling me what to believe without some proof. It's like a politician telling me the bill he is presenting that will reduce taxes for the rich will result in job creation. "My dear voter, you just need to have faith in me." You'll never hear me say, "Oh. Okay," as I walk away contentedly.
