I understand.
Facts based on science have also been revised, refuted and reversed. New information can and has changed what was assumed to be factual. We can only work with what we currently know (or think we know). We are limited in so many ways. We have the choice to trust in what we believe or keep digging to uncover what could be hiding from us. You are obviously content to stay with what you have learned. I will never be satisfied and will always keep digging. We are different and yet the same. If everyone thought exactly the same as everyone else, I think innovation and creativity would grind to a halt. It is through differences that discussions provide new ideas and avenues of thought.
When I think about what I just wrote, I can clearly see that everything has an opposite: Day and night, hot and cold, right and wrong. We need opposing beliefs as much as we need opposites in anything else... it maintains balance. I'm sure the Creator made it that way for a reason.
Speaking of changes to old beliefs: It seems the Dead Sea Scrolls have recently uncovered some ancient writings that were previously invisible to us. New information that changes the popular belief of what the Bible says. I guess it is time to up-date the Bible so that it more accurately reflects the original meaning.
