Personally I do not believe there is a God. I do, however, open my eyes and widen my range of religions to see what is out there. I'm not one of those people who throw others' religions out the window because of what I think is right. I love learning about all the religions out there, as well as cultures.
I don't think God exists because it's just not something possible. I know there are many odd, unexplainable things in the world, but having a place called Heaven, or even Hell, does not make me believe in it because others say there is. Catch what I'm saying? I can't believe in something that no one can prove besides having a bible at their side. The Bible does not mean it's real. For all anyone could know, the Bible is just another story for entertainment back in the very, very old ages. To top it off, the Bible was written many - hundreds - of years after Jesus. How can we know for sure that the Bible is remotely accurate and not exaggerated.
Anyway, those are my thoughts. I hope that it does not cause an argument since the topic is supposed to be a personal thought.
