Ever had that moment when Islam just clicked for you?

Salaam everyone, hope you're doing well. So I've been diving deep into learning about Islam, along with checking out other faiths too. Grew up Catholic, but these days I'm more on the agnostic side, to be honest. Currently, I'm really resonating with the Quran-it feels super consistent and every question I throw at it gets a solid answer. But here's my hiccup: just because the Quran doesn't contradict itself or clash with the world around us, does that automatically make Islam the truth? Like, there are plenty of fiction novels out there with zero contradictions, but that doesn't turn them into fact books, right? So what's the one thing about the Quran that really locked it in for you? Deep down, I wanna believe, but I also feel it wouldn't be right to call myself a Muslim without being totally certain. Hope that doesn't come off as silly lol. Appreciate you reading this! Basically, I don't spot any issues with the Quran, but no issues doesn't mean I should just accept it as fact. What specifically convinced you about Islam?
