How do you determine truth? What is truth? Does truth evolve? What's one thing you know for sure?(Note: The main question is "How do you determine truth?" Then there are "Dig deeper" supplementary questions that follow, and those questions are "What is truth? Does truth evolve? What's one thing you know for sure?" From now on, my format will be this: The main question first, and probably as the title of the post, and the supplementary questions following.)
I don't think it's always possible to determine truth. There are somethings that we will probably never know. For example, is there a god? I believe so, but I can't prove it to be true. I can't prove it to NOT be true, either. For some questions, there's just no way of knowing whether or not it is true.
