This must have been the silliest question which has troubled so many ingenious minds all through these centuries which came first
boiled eggs or kentucky fried chicken ?.. the egg or the chicken ?
So I made a search on wikipedia where the problem is extensively documented. How some people get such a kick from writing these kinds of stuff is even a bigger mystery for me :D.
Here is an extract ,
Since both the chicken and the egg create the other in certain circumstances (a chicken emerges from an egg; an egg is laid by a chicken) it is ambiguous which originally gave rise to the other. Purely logical attempts to resolve the dilemma result in an infinite regress, since an egg was caused by a chicken, which was caused by an egg, etc. Since every chicken originates from its egg, it seems obvious the egg came first.
My personal speculation is that Santa Claus came first , however this theory is overruled by many academics.
Here is another site which deals with the very exciting mystery.However be prepared for some incomprehensible explanation about the evolution of our common chickens.
