Why Do I Believe Islam Is True? Seeking Rational Proofs

Assalamu alaikum brothers and sisters, I come from a practicing Muslim family, and alhamdulillah, I try my best to follow the teachings of Islam. But lately, something has been bothering me. I feel like many of us, especially young people, just follow Islam because we were born into it, not because we truly understand why it's the truth. We claim it's the true religion, but can we back that up with reason? I'm someone who likes to look at things from a logical angle, so I asked myself: Why am I a Muslim? Is it only because my parents taught me? I do have strong faith and know some evidences, but I want to dive deeper. There are thousands of religions out there, and they all claim to be right. So if a non-Muslim asks me why I'm Muslim, what would I say? What's the rational basis? Please forgive me if I've said anything wrong-I'm just trying to learn and seek knowledge. Jazakallahu khair.
