Navigating doubt and seeking understanding in my faith

Assalamu alaikum everyone, I grew up in a home where Islam was more about tradition than deep exploration, and asking tough questions about faith wasn't really encouraged. I always considered myself a believer, but as I've gotten older, I've found myself wrestling with some serious doubts about my belief in Allah. Part of me looks at the incredible complexity of the world and the universe and feels there must be a Creator. I study neuroscience, and the intricate design of life and consciousness makes it hard for me to accept it all came from random chance or a single cosmic event. But then my heart struggles with other questions. If Allah is Al-Rahman, the Most Merciful, why is there so much suffering, especially for innocent children? We often hear that trials are a test or a consequence, but what about kids facing horrible illnesses or violence? The idea that they are guaranteed Jannah doesn't fully ease the pain of wondering why they must endure such hardship in the first place. It feels difficult to reconcile. There's still a strong feeling inside me that points towards Allah's existence. I'm genuinely seeking answers and resources to help strengthen my iman and understand these challenges better. If anyone can offer kind guidance or share knowledge that has helped them, I would be so grateful. Please respond with gentleness and empathy. I'm coming from a place of sincere confusion and a desire for support, not debate. Jazakum Allahu khayran.
