It’s not my favorite music, but a friend of mine recently passed away and I can’t get this music out of my head because we played it at his goodbye party when he went to live in another city. It’s in Portuguese and a music about goodbyes: Matanza - Tempo Ruim some rough translation below for those who don’t speak Portuguese:
Raise up your glasses for those about to leave
Long will be the road to follow
Nothing will be like it used to be, nothing will be easy for you
Don’t do the same that your father did
Don’t bring weapons where you’re going
So many I’ve seen paying to see, they didn’t had time to regret it.
Nothing you shouldn’t already know, there’s nothing you can’t have.
I wish the road always comes to you, and that the wind be ever in your favor. I wish you always have a beer on your hand and that you have your great love by your side.
I say goodbye to all of you, many here I will not see again.
Besides the winter and bad weather I don’t know what awaits me
But it doesn’t matter what it might be if some day I have someone to say:
I wish the road always comes to you, and that the wind be ever in your favor. I wish you always have a beer on your hand and that you have your great love by your side.

It’s the egg.
The way evolution works is that offspring might suffer mutations and not be 100% a copy of their parents DNA. As such, for any concrete definition of chicken there was a non-chicken that put a chicken egg.
There’s no argument for the chicken first, because a chicken needs to come from a chicken egg, but a chicken egg does not need to come from a chicken.
