I dont want answers that discuss:
1) the evolution of red junglefowl
2) origin of life,
exception: unless one of the four conditions of life is particularly important to the answer i do want. in other words, I dont want to be focused on ~3.9 BYA, I want to talk around the time of the evolution of egg-like multicellular reproduction (when was that? are there single cell eggs?)
anyways, I am guessing the egg comes first, because the organism(s) that finally went on to pass the egg laying trait was the first one hatched. that same organism may have been able to have fertile offspring with its non egg laying predecessors, but the egg thing caught on.
now before i get hammered by all you internet bullies, because I know how this site can be, please understand I am only guessing above, and I am looking for answers. As I find them myself I will post them here. I also know there are some smart, imaginative people here, and those who specialize in the stuff I want to know, who can give me a better answer i can get myself.
so finally, the question:
what came first the egg or the egg-layer? the egg can be soft, but it shouldnt be a spore or bacterial kernel (right?), so....Whats the story?

An egg is a cell. To begin with the egg and the egg-layer was the very same thing. A cell that made a copy of itself. So the simplest answer is both.
Later multicellular versions still reproduce by making single cells that subsequently develop into multicellular organisms. Some egg-layers simply lay the egg directly into the environment, others retain the egg-cell within their bodies and protect it while it develops, before laying a larger more complex egg with a protective shell and all that. As you can see, there is no clear demarcation between the first egg and the first egg-layer. It's all just cells making copies of themselves.
