1. Why you are here.
2. What will happen to you after you die.
Your beliefs are between you and your chosen deity. Your religious experiences are between you and the deity(s) you choose to communicate with.
So why all this religious trouble? It happens when people start speaking to each other about their beliefs.
Your beliefs are your own. They are part of what makes you special. But other people are different, so don't tread on their toes. Better still - don't speak about them.
Now, here's some ideas that might be less popular:
Religion is not law. Law is law. Law does not claim to tell you what happens when you die. Law does not attempt to explain why you are here. So why should religion try to make rules? Also, religions are not fair to all peoples because they are, by their nature, mutually exclusive. So therefore they are unable to rule all people equally.
Religion is not a reason why someone should be your friend, enemy or anything else other than another human being. If I have to explain this one, you need more help than I have time to give.
Religion is not a reason for doing anything on this planet (good or bad). Religion is - however - how you feel about yourself.
