We didn't evolve from monkeys. We evolved from a mutual ancestor of both man and apes.
Okay, you want a real answer, Nerezza? Here's the real answer.
The only reason mammals don't miscarry is because we have a piece of parasitic code hidden in our DNA that prevents us from detecting the foetus as an alien lifeform and ejecting it from our wombs. It gives us an evolutionary advantage because it allows us to carry our young in an environment that's perfectly designed for gestation.
Birds and reptiles don't have that piece of DNA. They have to lay eggs, which means not only are their young more at risk, but the parents are more at risk while protecting the eggs (if that's what the species does; some species just lay a lot of eggs and rely on numbers).
Birds evolved from dinosaurs (ie, reptiles), and just like the common ancestor between man and ape, those dinosaurs are now extinct. They're like an experiment that nature did, testing out the design and then scrapping it for a better one.
So your egg? The thing that laid it was a wild fowl. Because wild fowl is what we (humans) created domestic chickens from. So literally, the egg has to come first, because the first chicken was created by humans by domesticating wild fowl.
But man didn't evolve from monkeys. At least, not modern ones. Man just has a common ancestor with monkeys. But if you look at it that way, we also have a common ancestor with bacteria.
