I have yet to take physics in highschool (will next year...) but a good friend of mine told me that the Big Bang Theory defies the laws of physics, such as energy/ matter cannot be created or destroyed so how would the BBT be possible, also something about how everything tends to dissorder, so why would the world create an ordered world, then go back to tending to dissorder??? Just wondering if this is true, and what everyone else thinks...

Big Bang Theory is just a 'Theory'. It was the only theory that had a suitable explanation thats why it has been universely accepted. No one ever said it is true..its just somehting that scientists came up with so people would stop asking the question ' Where did the world come from?'
You can believe if you choose to or just keep wondering from where it all started.
The Big Bang Theory : It is believed that the whole universe occupied a small volume in space and a big explosion took place in the universe and since then the universe has been expanding. It is estimated this took place 15 billion years ago.

When you learn the actual laws of physics, you will see why all the evidence points to a beginning in a singularity, and how the universe evolved from the initial expansion. It follows basic physical laws that you can test yourself
As to where it all came from in the first place, we're not sure yet. All evidence points to a beginning in a singularity, and we have a lot of ideas as to how it might have happened (but none you'll learn about before you get to grad school in physics, if you are actually interested - definitely not in high school). Those ideas are testable with upcoming instruments, but not currently.
Don't worry. Very smart people who understand physics very well are working on big bang theory. You can remind your friend about that and ask him about HIS phd in physics, since he obvioulsy understands it so well.

What it defies is logic. People say that it's believable (and even true) that a bunch of cosmic debris collided together and somehow formed the earth and everything on it yet they totally dismiss the idea that God even exists (let alone that He created the world) because they think that it is so more far fetched than the Big Bang theory.

no no... big bang has nothing to do with the creation or destruction of matter... a better name would be big "expansion"... big bang was simply an expansion of the universe itself (space). also, if you look at the universe as whole, it has cooled alot (from billions of degrees K to just few degrees above abs zero), which means entropy has actually increased (thus more disorder), and does not violate the 2nd law of thermodynamics (if that was what your friend was talking about).

that's why Steven Hawkins said it wasn't possible. years after he made the theory.
