It's absolutely worth doing the research. I am pursuing it myself, although not very systematically or comprehensively. But what I do see:
- Islam's strength is tht it is very simple. After your accept just a few premises, everything seems to fall into place. There isn't anything complicated like a 3,000 year history (documentable) or a theology involving a fall from grace, a flawed human nature (resulting from original sin), the need for a Savior, the Blessed Trinity, the incarnation of Christ,and all those seemingly complicated things.
- Islam's fragility is tht it has no historic basis. Look back far enough for any evidence --- any at all -- and it just falls apart.
I think that's one reason why Muslims blow up historic sites (Egyptian, Chinese, Buddhist, Hindu, Jewish, Christian) and always have. The external evidence is that Islam in fact did NOT exist before Mohammad. It's very plain that no ancient people
anywhere were Muslims before Mohammad.
To this day, Islamic "scholars" sternly forbid Muslims to do serious evidence-based study about the ancient history or "roots" of any culture --- inluding their own!
