questions from an agnostic

hey all! im super curious about religion, ive always been the type of "spirtual" esque person where I believe in myself but also believe in the "universe." I haven't really solidified how I freely about that exactly. I want to learn more about each religion and become myself from that. Buddhism and Paganism have always caught my eye but I want to learn more about Christainity and Islam.

I have a few questions -

. was jesus a real person? are there facts and proof of his existence on Earth?

^ If so, I've heard from people that different religions have the same idea. You speak to Jesus to get through God. You speak to Muhammad to get to Allah. If there's proof of existence for Jesus - is there proof of existence to Muhammad?

. I've heard the phrase God works in mysterious ways. I'm curious about this too. What does God do in your religion? Is he an all loving - all saving person? What is the explanation for tragedies and what is the explanation for like single cases? A depressed kid praying to God to be saved but he doesn't. What is Gods role in these?

. Why did you start believing in Religion? Is community a big aspect?

^ I love the idea of community. I think community is needed and I think religion is a helpful part in that and bonding. That's why I find churches nice.

. Is there a most accurate version of the bible?
