Seeking Guidance Through Doubt

Salam, I'm not sure how to begin. I just turned 18, and lately, I've been wrestling with some uncertainties about my faith. A bit about me: I'm from the UAE, raised in a Muslim family, and Islam has always been a huge part of my life. A few months ago, during an Islamic class, a friend mentioned something that sparked two big questions for me: How do we know Allah and the Prophet ﷺ truly existed? He didn't have answers, so I started researching-exploring different perspectives, learning about philosophy, and reading works like those of Ibn Rushd. I've been trying to think logically and deeply, but it's led to doubt. I'm reaching out for help because I haven't found clear answers yet. I understand Islam encourages seeking knowledge and reflection, but when I look at the Quran and Hadith, some things don't logically click for me. There's still a part of me that wants to believe, and I'd really appreciate any advice or explanations to help me through this. Jazakum Allah khair for reading-I'll carefully go through any responses.
