What was before,the egg or the chicken?

It is a very complicated question.

But... Why?

Because,a person can think that the answer stay in internet,and,later to read it,this person "knows" the aswer. But... What do you think about the possibility that another person could think that the answer is not completely studied?

Greek philosopher Aristotle (Aristóteles) always said that is always present before the potential, the man always precedes the sperm, and the chicken precedes the egg.

Really, a lot of philosophers,scientifics and other persons have a lot of explanation for this answer,but... I am going to choose the most "popular answer" so... Are you ready?

So,the correct anser about it,is,definitely that the egg was before tha chicken

So,after this,I would like that you comment about this item.
