Aha, now we have a debate at hand.
Laws are proven in all situations.
Was Newton's Physics not accepted as "law" before Einstein? The term "law" is actually misleading in the modern context of science. The term was originally introduced by scholastic thinkers who thought that just like God uses moral laws to determine human behavior, he also has "laws" that dictate how the world works. However, that is not how science uses these things anymore. The "law" of gravity does not cause things to fall. The way things behave, with respect to attraction, is best described by gravity, even if we have yet to discover what actually causes this. (Graviton proposed, but we don't really know yet)
Scientific Theories therefore cannot ever contradict one another
Of course they cannot. Scientific theories and laws have the aim to most accurately DESCRIBE and PREDICT how the world operates. However, they can never with 100% certainty say that something is impossible. They only give descriptions of what is really really really really unlikely.
But when you use the term "impossible" you leave science behind and enter the world of logic and metaphysics. And in those terms, the word "impossible" carries a lot of force. And such force can only be produced by a deductive argument, the premises of which CANNOT by the rules of logic come from the conclusion of an inductive argument.
if that were true, it would be in the bible, so that's not true.
Now, of course not if you read it as a literal 7 days. But I am just saying possibility here. And we have creation of earth, universe, sun, stars, plants, animals, people. It never says HOW he does it. It just says "he created" and "let there be stuff." Now, to even turn a popular argument upside down, obviously whoever wrote/edited Genesis 1 and 2 saw the two chapters at the same time, and if to him and was not too important to get the order completely precise, then maybe that isn't about order at all. The point of Genesis 1-3 is that God made it all, but it is not how he made it. Now, I think he could have done it anywhere from 7 day 10.000 year earth to 13.8 billion years big bang and evolution, and everything in between. You CAN read the text either way and still be true to it. All I am saying is, don't get hung up on this one, it's too petty to argue over if you do not believe the Bible anyways.
In literal sense, yes. Everything is made of matter and has energy, therefore only those things exist. Everything that exists other than matter and energy are made of matter and energy.
That is, everything known to our section of the human race.
Ok, you are making two seperate claims here.
1. Everything is made of matter and has energy, therefore only those things exist.
2. We (humans) only know about matter and energy.
Which of course entails
3. We humans know about matter and energy.
What I am wondering then, is if you hold to 2., how do you know that 1. is true?
Also, how do you know that 3 is true? Let me clarify. I am not asking "How do you know we do not know anything else?" I am asking, "how do you know that that statement is true?"
Ok, let me play with open cards here. I am wondering how, as a naturalist (only matter and energy exists) do you know anything? How do you ground your knowledge?
