My bad, I was making a different point with that analogy, and I had moved on some time ago. The app I’m using makes it difficult to read back up the thread.

I think we are making similar arguments. I would say that the egg Amy hatched from is the first “chicken’s egg”, but it is only the first chicken’s egg because it belongs to Amy, and it did not exist until chicken-Amy existed, which was some time well after the egg was laid.

Sorry, I’m getting distracted with real life right now.
