Why should everyone's religion have a specific criteria?

As long as you're happy with your beliefs and don't critisize other people for theirs, then it's all good.

Everybody sees everything with different eyes, I don't think there shoud be a specific religion for an amount of people.

There's no proof for anything in life, deep down it's always theory.
So what's the point in fighting an endless battle of questions, when YOU as a person are the answer to everything. Only you can control what you think and that's what matters. Your mind has to rest in peace with your thoughts, so whichever religion/mentality that's supposed to be, it doesn't matter. At the end of the day we're all the same. Instead of fighting a war of different opinion, we should learn from every single one.
