I believe in a mixture of my own things. I do find that almost every religion i heard about makes sense though. I'm actually jealous of people whose brother or father or son passed away, and then they're somewhat fine with it because they feel like it's what their god wanted.
I believe that there's some kind of god, but what one? I don't know. I believe in ghosts/spirits, fate, karma and reincarnation, but that doesn't make me believe in a certain god. My ideas are very personal and I am absolutely fine with the fact that others think what I believe in is bullshit.
It's something you have to decide for yourself.
