It’s honestly my best evidence this really is all a projection.

If (from the light’s perspective) it just left and arrived instantly, that really supports the idea it’s just a hologram appearing as summoned rather than a static entity thats existed billions of years despite no one seeing it. It’s really screams like we saw it and then made up an explanation to explain how its actually really old and took time to arrive when our science is pointing out it actually just appeared at the very moment we saw it.
