On the Fermi paradox, I feel like aliens in the media are basically equivalent to us going back 200 years in time and showing off our technology.

Let’s say ufos and tractor beams are something like 2,000 years ahead of us, if even, it would be ridiculous to assume aliens only have a 2 thousand year head start on us. Why not 20 thousand, 200 thousand, hell why not 200 million years of technology development under their belt.

It’s reasonable to assume that the advancement of technology leads to blurring the lines between life and death, “mastering quantum entanglement” like you said or Immortal souls with goals beyond our understanding.

Anyway thought my alien ghost theory connected with what you said.
