Nature's Laws

[robvalue]

Hello welcome to the forum

How could impersonal stuff like matter and energy "obey" laws of any kind?

This is assigning agency to things that aren't making any decisions. They aren't obeying because they're not thinking. It's more accurate to say they follow the laws. We describe how the universe works, we can't ever know exactly why things are the way they are.

Where do the laws of nature and the laws of logic come from?

We don't know. Just making up an answer and requiring someone prove you wrong is the argument from ignorance fallacy. You still need positive evidence for your claim.

If there is no god, why do so many atheists care so much about the non-existence of a supposedly fictional deity?

Most atheists don't claim there is no god, they claim there isn't good enough reason to think that there is a god.
