You don't understand. Those are still " how" questions. All it answers is how things function. It doesn't answer why they should even exist or why laws of science exist. Why is there order instead of chaos? Why do we desire God?
I disagree. They are 'why' questions and they get answers from science.
Why is TNT explosive? because of the instability of the bonds in the molecule. That is an answer to 'why'.
Yes, it answers how things function. That *is* an answer to 'why' things do what they do.
Now, you want answers to why anything at all exists. Sorry, that isn't a question that *can* be answered. But *you* can't answer it either.
For me, the question of why the universe exists cannot be answered. It just exists. For you, the question of why God exists cannot be answered. He just exists. But I know the universe exists and you can't prove God does.
The laws of physics exist because things in the universe have properties. Why do they have properties? That cannot be answered: no cause can be given because the action of a cause is the same as a property.
As for why you 'desire God', I would guess it is because of your upbringing.
