Which came first: The egg or the chicken?

There are many theories revolving around the question that, "which came first: the egg or the chicken"? The answer also varies from theory to theory. In one theory it is said that egg came first and in the other one it is said that the chicken came first. The answer is not clear because no one saw it coming. 

But according to me these are the conclusions without any scientific evidences, so don't take them seriously, these are just for jest, have fun. 

If we go literally by the words chicken or egg then the answer is egg. Because eggs were laid even by the dinosaurs and the dinosaurs came way earlier than the chickens so, in this case egg came first. 

As you can see the winner of the first round is the egg. Here, the egg came first and the chicken came next. So, the next time when someone asks you, what came first - the egg or the chicken? Then with this theory you can explain them that the egg came first. 

It is also believed that all the birds are oviparous, it means that they are egg laying animals. The ancestors of the chicken are also birds, that maybe the reason that they have got feathers and wings. If their ancestors are birds then ultimately chicken is also  an oviparous bird. 

If they had been viviparous then they wouldn't have been laying eggs, they would have directly given birth to their offsprings. So, this theory states that if the immediate ancestors of chicken were laying eggs then the chicken would have come out of that egg and then in the later stages of it's life the chicken also started laying eggs and those eggs would have grown into a chicken and laid eggs and so on.... So, here also the egg came first then came the chicken. 

As you can see the winner of the second round is also the egg. So, there is more probability that the egg came first and the chicken came next. 

So the answer for the above question, which came first: the egg or the chicken? Then, for this question the answer is EGG.
