In a court of law it is often extremely hard to arrive at a simple and unambiguous truth Not really, either their is enough proof to convict or there isn't.
you have to decide on the basis of the evidence which is more probable Not really, either their is enough evidence to show what is true or you admit you dont know. You don't pick the least worse theory and say it is therefore true.
Even in the supposed 'hard' sciences there are often areas of doubt and uncertainty No there really isn't. There is only uncertainly until the answer is reached when there is then certainty. And there definitely is not two different things that are equally true at the same time, what ever that means?
we can long for everything to be plain and straightforward, but in reality the cosmos isn't like that
That's exactly how the universe is, A is followed by B is followed by C and on until you reach the truth, plain and simple.
In history, you have to look at the evidence; and the same in a court of law; and the same in science Which is what many have tried to do and the evidence points to the straight forward conclusion that there is not enough evidence to conclude anything.
It's somewhere in the fuzzy middle between totally simple and completely individual Which is more succinctly phrased as 'I don't know', not 'definitely true'.
it's entirely possible that Jesus came to bring us a true message, but for us still to be interpreting it 2000 years later Any if we follow the evidence it concludes we dont know if there was a supernatural Jesus, and even if there was we have no way of knowing which of the million different messages espoused, if any, he brought.
So it brings me back to the beginning, unless you take a punt the Book is literally true, there seems no way to know what it really means, in which case you study and take a punt on the least worse option.
