No, they wrote the description of the law they did not write the law themselves. If there was no law then there would be nothing to describe. I am not referring to scientific laws, I am referring to the laws of physics or nature. They exist independently of what scientists say or do. Scientists discover them and then try to describe them. Not always correctly of course.
No, the law describes an aspect of the universe, not the other way around.
A scientist may discover some phenomenon or aspect of the universe as we know it, and write a law or theory to describe what they have discovered (It would likely start as a hypothesis and progress from there, but I'm simplifying the post for brevity).
Because without an orderly and lawful universe then it would unintelligible thus making science impossible.
Which has nothing to do with a god existing. What makes you think a naturally occurring universe would be an utterly chaotic mess? You're making an unjustified assumption. Why wouldn't a naturally occurring universe operate in ways consistent with nature?
No, not really. You haven't made anything remotely approaching a solid case for this assertion.
It could be just a realistic dream. No, He is very relevant. Without Him you have no rational basis for believing that what you are observing is objectively real.
Well, if you think it's plausible that this is all just a realistic dream, then what makes you think a god is required in the "real waking world"? If this is just a dream state, then perhaps god is just an aspect of your own dreams.
In reality you have no demonstrable objective basis when you appeal to god. You have a claim that you can't demonstrate, whether this is all a dream or not.
No, you need a correlation between what you are observing and what is actually there for real science to occur. And without a creator God you have to make an irrational leap of faith to believe that what you are seeing is real.
Your argument is a complete non sequitur. The universe is as it is, whether a god created it or not.
Your assertion that a god is required for me to believe what I'm seeing is real is utter nonsense. Why is that god required for me to justifiably believe I'm currently typing this message on my keyboard? All the available evidence pretty conclusively shows that I'm typing this message on my keyboard.
Whether there is or is not a god, I'm still typing this same message on the same keyboard. All the evidence I have available to me is exactly the same. So why would a lack of a god's existence give me credible reason to believe I'm not experiencing reality?
It makes no sense at all, your logic does not follow.
