I mean… I appreciate the long-winded explanation of how light moves through space, but none of it covers how space itself expands and how that can make distant objects move away from us at faster than light.
Again, the galaxies are not moving through space faster than light, but the distance between us and them is growing faster than light-speed because of the expansion of space.
They are effectively moving away faster than light. If you magically took off toward one today at light speed, you’d never reach it.

Missed that, you're quite right there, space itself is expanding.
