The theories based on Space though are still just that theories because we don't spend enough time there to see how well everything holds up. The laws of physics are invariant??? The laws of physics have always been there they are laws because that is how we define them. Can it be possible that as imperfect human beings we might be wrong on how we defined some of them??
You might want to pick up a book or two on the subject.

There's no such thing as a "theory based on space". Mind you, I think I know what you mean, but, well... it's just wrong.

Regarding being told how the earth was formed: It's the same reason they teach that electrons circle a nucleus like a planet around the sun -- it's wrong, but you're not at the necessary level to understand the (for lack of a better word) 'truth' behind it. Ditto with the law of conservation of energy. It's true, but not really, but still must hold. You can borrow small amounts of energy from the universe, as long as you give it back in a small enough (read: near-Planck) time. There's much to learn before one can grasp planetary formations of astrophysics or electon distributions and quantum field theory of high-energy physics. So, at the introductory levels, there's certainly much to be desired, and the smart student will often recognize this and find the knowledge being taught very incomplete.
