More people believe in Islam, maybe that's the truth. You haven't answered a single question I've posed other than "I don't know". In fact, your reason for not answering is "You're a layman, so your questions are invalid". That doesn't give me a whole lot of reasons to think I'm wrong - you basically just reversed your appeal to authority argument but you still haven't actually answered my questions.

If the answer is, "We don't know", then great - we're on the same page.
