<p>A scientific theory is as close as it gets a fact. The only reason we call it a theory instead of a law is because we cannot sense it with our own eyes. Relativity is a theory because we haven't been able to travel at the speed of light. We cannot "see" atoms, so it's also a theory (maybe we can see them now with electron microscopes). Electromagnetism is also a theory.</p>
<p>Evolution is compatible with the Bible because God's notion of time could be different (perhaps he's just traveling in a different frame of reference, and that frame of reference changes with each different day. On the first day, he might travel at .99999c, meaning his time slows down and 1 of his days is equal to billions of our years, the 6th day, .9c, and when he spoke to Moses, the same as people on earth travel)</p>
