>1. How do you know that God has no reasons for allowing evil?
So you accept that your god is either a) unable to stop suffering (not-omnipotent) or b) unwilling (not-omnibenevolent).
It's mindbogglingly simple to defeat your argument here I'm sorry, what possible reasons could an all loving god have for allowing suffering? Any reasons to not cleanse existence of all suffering could also be defeated/altered/removed (see: omnipotence).
I replaced the word evil with suffering because evil is a symantical nightmare.
>2. What would you accept as evidence for God's existence?
God doesn't exist, at least not the way you or I understand existence. Supernatural beings by definition can't exist because nothing that we understand to really exist exists outside of nature, I suppose you'd need to define a realm of super existence where god can exist and you'd have to demonstrate that that realm really exists in some demonstrable way and then you'd have to demonstrate that your god exists there.
>3. Would you believe in a miracle if you saw it?
Not immediately no, if it was later demonstrated that a supernatural force acted in the natural universe then I would be forced to believe it.
Sight is an easily defeated sense, I guess you would know that if you'd seen an illusionist perform.
>4. Do you think the cause of nature is natural?
Why not? Also why can't nature just be eternal? If your deity is allowed to be eternal why can't the natural universe? Of course space-time has a finite beginning but that doesn't necessarily mean that nature hasn't always been there.
>5. Do people who do bad things deserve to be punished?
I believe in the rule of law, people should be punished not because of divine retribution but because it leads to better societies, it's better for the human collective that bad-actors are punished. Do they "deserve" punishment? No, but I would like it that all bad-actors were punished because then there would be less bad-actors.
