Everything exists in the mind of God. Imagine the universe as drawing a circle on on paper. Now draw an even bigger circle around that circle. That is the mind of God.
And now we see the idealism of George Berkeley paraded into this inane discussion.
A thought experiment. One hundred people go one bu one to a desk where and object is in an open box. They write down what they see in the box and deposit that slip into a box. Then the observations are tallied. One hundred people see a red coffee cup in the box. How can that be? If things exist only when observed, how can everybody see a red coffee cup. Idealism problem of persistent objects.
Berkeley's answer was God observed all. So the red coffee cup was persistent and never disappeared. Now we consider an evil man, John, who is torturing innocent Jane. If God decided to no longer observe John's instruments of torture, or even John, they would disappear. This then seems to make the allegedly perfectly good God and accomplice to all horrible actions and crimes of evil men and women. How does this God observes everything work?
We also get into the problem of if God is inside or outside of time. If God is outside of time and sees all at once, all that is exists and Gods sees it all. And created it all at once and so is responsible for it all, including John and his instruments of torture and the hapless Jane.
This is just the beginning of the problems of God for theology and idealism.
