Well, lets take a logical approach. Obviously a chicken hatches from an egg. So therefor the egg must come first. BUT you need the chicken there first to lay the egg. How did that chicken get there though? he needed to be hatched out of an egg. Of course that egg needed to be layed by some chicken. Could the chicken have came one day when, lets say an owl and a duck cross breeded? Then the chicken came first. well not really, it depends on if the duck layed an egg or just popped that chicken out. Maybe some sort of other bird, lets say an ostrich layed an egg and something was wrong with it, so it was much smaller and different than the rest of them. It was hatched and remained smaller. so they called it a chicken. so the egg came first.
Man, i dunno, i'll just blame it on the government. HEY! maybe there is no such thing as a chicken or an egg, maybe the government brainwashed us into believing that they exist so we will spend hours contemplating this very question. Thus, taking our minds away from the fact that they are screwing us over every chance they get. Well, i'm no government stooge....i will not be putty in their hands and contemplate this subject anymore!!
