The “edge” we see is just the furthest point in the universe that light is able to reach us from. Beyond that the universe is receding too quickly for the light to make it to us. Since the expansion is uniform, we can see an equal distance in all directions and thus we are at the center of our visible universe.
According to current theories, the Big Bang happened everywhere at once, so there was no center. One somewhat useful analogy is an inflating balloon; the entire surface of the balloon is expanding, but there’s no center to the expansion.
