Seeing is Believing?

This post is in response to the question from Cronin's Thought Maze: "Do you believe there is more to life than what we see? "

I think there are certainly things out there that we have not discovered yet. And I also think that there can be things on earth or in the spiritual realm that we cannot see but we must just believe or choose not to. A lot of people choose only to believe something once they have seen it for themselves with their own eyes. Seeing is Believing. But sometimes just having faith in something can make the belief stronger as was said in the blog. Believing is Seeing. Once you truly believe in something, it will open you up to so much more and faith can be guided by something strong. If we rely on only what we see, life would not be nearly as interesting as it is if we take risks and believe in things that we cannot neccessarily see for ourselves. Take the idea of ghosts and the spiritual world. There are people who believe in them, people who are skeptical, and people who don't believe in this at all. Either way, the possibility that something like a ghost from the past could haunt a place, object, or person makes for an interesting idea and brings up debates about beliefs and faith.

What do you think about the supernatural world?
Are we being tricked? Is there something else really out there?
