Knowing that evolution is a more plausible reason than 'creationism' is better for the same reason that knowing that the Earth revolves around the Sun and not vice-versa. Knowing true facts is always better than knowing bogus ones.
All sexuality develops around the time of adolescence, so it is not uncommon that a gay orientation would develop 'later in life'.
I don't think that gay people are per se more successful in life than hetero people, or less so. It is highly probable, however that gay people in the Castro of SF are more productive, for the same reason that people that live in Tribeca or near Central Park in Manhattan are more productive: one must have money to live there, and one must be productive to have money as a rule.
The various books of the Bible were probably NOT written by their alleged authors. Authorship was nopt seen than as it is now. If I felt that St Peter or St John had inspired me, I could easily claim that they, not me, was responsible for whatever it was that I wrote. If what I wrote was closer to what the Church heirarchy believed or found convenient, my writings could actually be chosen over those of a real disciple.
What was the probability that a simple fisherman like Peter was literate?
It is not at all clear that Jesus was literate. There is no record of him ever writing anything, to anyone.
