Proof that I'm immortal

[Angrboda]

No offense, but bringing significance and meaning into the world is a consequence of biology and evolution.  Saying it doesn't exist outside that is not a very meaningful critique.

What do you think I'm critiquing?

You seem to be critiquing human meaning by pointing out that it doesn't exist outside of sentient beings. That seems an awful lot like complaining that there are no land-locked states along the shore. It leads to a so what moment. If you're going to critique ego and human meaning, you're going to need to do it on its own terms, otherwise you're just making category errors.
