Hard to wrap my mind around this one. Anyone have any good analogies that fit?

The balloon analogy requires scaling everything back by one dimension.
Imagine the surface of a balloon is a 2-D universe. Nothing exists except what’s on the surface. The curvature of the surface isn’t obvious but some scientists theorize that it’s somehow ‘curved’. It has no edges or boundaries, but someone on this 2D universe discovers that every point on the surface is getting further apart from every other point. A theory is formulated that the entire balloon surface was once much smaller and started at one point, and it’s been expanding ever since. Which spot on the balloon was at this creation point? All of them. It’s been expanding through an unknown and unfathomable extra dimension that nobody on the surface can even conceive of.
