I commend you for having read the Bible 5 times already. Most people don't even read it. haha.

Anyway you can easily find the answer to your questions online. I apologize but it is too lengthy to get into and I am not the best person to answer them. Feel free to even use Truthly AI or any other AI so you will know where it is written according to Catholic teachings. Just make sure it is from reputable Catholic sources. God bless your spiritual journey. 🙏
