I say welcome to both of you! There is a lot of great information here, but also be aware that the Fantasy and trick sections are there for a reason.
Mady, your friends may say none of it is real for a lot of reasons, but every time I see someone (usually some other board than this) trying to challenge magic users to proof, they are only ever referring to fantasy type magic, as it appears in movies and fiction books; that is, the shooting flames, growing wings, becoming invisible, levitating objects, and other such silly things.
In fact, there are many adults out there who are somehow convinced that magic does that, though they never try to find out on their own.
But please: Bear with us, learn a bit, and do some reading on your own! There is a lot of great information to learn.
