I can answer for only myself here..yes. I have questioned and examined the proofs and decided on Islam as my religion. See I was not born into a religious family. Far from it! So I'm not a person who blind followed anyone,Alhamdullilah.I chose Islam after many years of researching and questioning.And I truly believe Islam and the Quran is revealed by God.That's what makes me a Muslim. Again if I believed all religions are man made then I will of course not be a Muslim. But that doesn't mean I've abandoned seeking knowledge be it of my religion or outside of it. In fact the more I learn the stronger I become in my faith..which ultimately is what IMO it boils down to in any deferred and debated matter and in any school of thought. belief,faith and conviction.
