Nope, just extra dimensional cause for creation, no higher purpose required, for all we know whenever two rocks collide in that scenario they create a universe.

Also no, you’re completely missing the point, if God is omnipotent he could have made humans to never suffer and still be free, in theory most Christians believe that Heaven is free of suffering, do you cease being yourself when you go to heaven then? Just because you or I can’t imagine a world where humans are free but can’t hurt one another doesn’t mean that’s beyond the realm of possibilities, and if your counter argument will be that then we wouldn’t really be free, I tell you that humans can’t explode someone by looking at them, so he already imposed some limitations on the amount of harm we could cause to each other, yet you don’t see this as less freedom because you just accepted that’s the natural state, I propose there could be a natural state where humans can’t cause harm to each other and are still free.
