Truth, like I have mentioned before, is like 6 blind men trying to see an elephant. They all see the elephant differently. And we all see the truth differently. Just because one person's truth does not match what someone else believes, does not necessarily make either of them wrong.
I remember in college, in Biology 403 & 404, Dr. F. would tell us that there is truth, and there is absolute truth. Truth is what we believe to be true. Absolute truth is what the universe knows is true. And he told us that what he was teaching us, we could learn tomorrow was all wrong. This happened to Newton as well as Einstein. Newton did not know about binary stars. Einstein did not know about quantum physics. These newer discoveries did not fit their theories. Yet, we still learn from Newton and Einstein, and we expand upon their truths.
