But that happens in all galaxies and has been happening eternally...are you suggesting that this milky way galaxy is the first galaxy to produce sentient beings?
No, I'm implying that even if living beings have existed for all of eternity their specific sentience has not.
Their consciousness is not eternal, nor are their bodies.
However, bodies can be recycled but the specific way someone perceives life cannot.
You cannot, to my knowledge, recycle a consciousness.
Therefore, consciousnesses came from something and ends in nothing.
That is my thinking, feel free to sway it.
