There’s a silly question that maybe you ever heard of; which comes first, chicken or egg?
To answer this question, we must first know which side you are standing on. If you believe in evolution, the evolutionist say that egg comes first.  Something about ‘zygote cell is the only place where DNA mutations could produce a new animal, and the zygote cell is housed in the chicken’s egg’. Or in simple word, the change on chicken DNA can only happens in egg. You can read the full story in How Things Work.
But, if you believe in religion and you believe God created animals, then it is chicken which comes first.
So, what’s the answer for this question? It’s for you to decide which you are going to believe. For me,  chicken it is. Long live chicken! And sorry for eating you (and your child-to-be, the egg) almost everyday.
