Magic Forums

I got bored one night at work and found this site. I've always been a huge fan of magic userswhen I play rpg games and stuff. Its my choice of character because its very interesting what can be done. I never really thought though that it could somewhat exist until the other night when I was bored I was like I'm going to do a google search and see where it came from and stuff. I then came across this site and I have been looking around a bit. Its a very interesting site indeed but I don't understand the concept of magic use or anything that, frankly I don't know if it really even exist.
I decided to join this site to see how it is possible for someone to do this or even if it is possible. I see all kinds of spells and such around but I don't see real proof of its existance. So basically I'm asking how am I suppose to believe in something like this which I really would love to, if there is no proof of it happening and if it does happen how do I get others to believe in it so they don't just laugh at me. I'm talking about real friends that all say the same as me and enjoy the same as me.
Any iformation would be appreciated to make me believe more into it. I believe in some things like this that could maybe in someway happen but I have never seen it happen. I hope you all know what I mean when I say this.
