OTWO. I did the same as you and agree it's up to each one to research for themselves as to whether their belief system has any historical support.
Faith, on the other hand is something different and personal to each believer.
It would take along list of the books I have researched and read over the years from A to Z on all kinds of topics, too many to list.
Once in a while I might recommend a book or two that someone here recommended to me and that I found to be very helpful.
