How does a reasonable doubt arise ?

It is very important that a person can one day become fully aware that he is definitely not a know-all and all-right.

When you have no doubt or absolutely no doubt, most time, it means you are wrong, but you are too much into your self belief that you have absolutely no clue that you are wrong.

So the system kicks into place, more events unfold and more stories are told to further confirm that you are right all along.

Then all of the sudden, out of the blue, thing takes a 180 degree turns, you start to have your own doubt.

It is the work of a reasonable doubt that to prove to yourself that your initial firm belief is actually wrong, even thought the whole process takes a very long 17 years to conclude.
