Truth is a very difficult thing to nail down. It can be a slippery customer. T here is eternal truth and truth of the moment. If I say it’s midnight , I have to clarify which time zone I am referring to. If it really is midnight in that zone, I have spoken the truth. A moment later it’s no longer midnight . The claim was true at the time, so I made a true statement. If I believe it to be midnight but my watch is slow, I have been tricked into making a false claim. So truth will always depend on accurate information.
That’s a very simple example. More complicated claims can be impossible to prove. Therefore we can only unanimously accept something as true when it has been proven. It has been said that everyone has their own truth. This is true but refers to subjective truth.
Being human we still have a limited view of the world and universe. Most of the mysteries of the universe are beyond our ability to prove, so for the present they remain mysteries. As humans we have very poor tools for establishing absolute truth in abstract things so sometimes 'accepted truth' is arrived at by consensus, as in a court case.
That's my take on truth but it won't be entirely accurate because the subject is much bigger than me.
