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

Imagine you’re a microscopic organism living on a bubble that got formed from someone blowing through a bubble wand. Your universe is the bubble. The bubble didn’t start at a single point (from your frame of reference), it just got bigger as it expanded. From a human’s perspective, you can point to where the bubble is and where it started, but to something whose entire existence is within the bubble, the Big Blow didn’t happen at any single point, but it happened everywhere on the bubble at once.
