I can only say the truth is relative.
There can only be one absolute truth with regards to any situation. The question to ask is "who, if anyone, knows the absolute truth".
Take the classic example of a car accident. The police come and ask 5 witnesses a "what happened?". They all tell a different story, but neither are lying. They tell what they heard and what they saw - from thier angle and perspective.
Then you have the drivers who are not necessarily lying, but you have to discount atleast some of what they say like "i was only doing 25 mph".
The point is there are 5 "true stories" but only one real truth which will likely never be known.
Take this idea and apply it to events that were not witnessed by anyone and you certainly will never know. People will come up with theories and create models and do experiemnts that will "prove" thier idea of what happened - but then so can a dozen others.
So although again, there is an absolute truth, there's no way to know. That's whay we have faith.
You can put your faith in your favorite scientist and accept what he says as the truth. But it's still faith and not necessarily the truth.
