What are Possible Worlds? (Also, God exists)?

Possible worlds are like imaginary lands you can visit when you're dreaming or playing make-believe, except they’re not just for kids, they help grown-ups think about big ideas, even whether God exists!

Think of a possible world as one of those cool block sets. Each set has different pieces, maybe some have red blocks, others blue or green. In one world, you might always build the tallest tower. In another, you might live in a house made entirely of cubes! These are all just different ways things could be, like different games you can play with your blocks.

Now imagine there’s someone, let's call them God, who has all the block sets. They’re not just making one world, but every single possible one! That means if you believe God exists, they could be behind all those cool imaginary lands.

So when people say "God exists," it might mean that God is like the Block Master of all the possible worlds, and everything you can imagine or dream up is part of their big, blocky fun.
