In need of a little faith

I hope it's okay if I post this on this subreddit lol

I was born in a family of Christians, so being Christian myself came naturally. The only odd one out is my uncle (very chill awesome dude), and I'm lucky to say that my family would still supportive even if I changed my views on religion.

And the more time I spend on the internet, the more confused I get in my faith.

I've been trying to strengthen the faith I have— yet the more research I do, the more.. less I feel like my religion is real.

There's a lot of.. holes in Christianity, to put it roughly. Like race, for example (there are a lot more examples, trust me).

If our Lord truly is kind and forgiving, why let so many people suffer? So many animals? So many things...

Btw, I'm under 18 (won't state my exact age, but it's below 17, too), so I'd appreciate if anyone who replies, is kinda less mean if I'm being ignorant (which I apologize for if I am.)

Religion is a complex and interesting concept, that, unfortunately, I don't get taught about a lot, if at all. But there I come from, I'd say about 80-90% are all Christians. I'd like something to strengthen my relationship with God, please!
