Contest // Topic of the week №2 // Egg or chicken?

Hello noble members of this community that is @slon21veka. I hope y'all are having a wonderful weekend. This weekend is treating me quite well.
Well this actually my first post in this community. I was introduced to the community by @mukadas a friend. Thanks for the recommendation though.

Moving on to the contest,which is asking us that between egg and chicken which one of it came into being first. This question is an old argument that has been there for decades. There hasn't been any clear explanation to the question so far. Because no body was there at the beginning to witness which one came into being first. Whether it's the egg or the chicken.

Eggs has been around the animal kingdom for a while. Eggs are just vessels that keeps an embryo in it till it fully develops and then it hatches.
Scientifically, the first chicken is presumed to be as a result of a genetic mutation that occurred in a zygote which was produced by two animals(birds). The coming together of the two different DNA's resulted to the formation of the first chicken.

In the scientific view above, it is the egg that came first into being before the chicken .
This is because of the mutation that occurred.

Another Scientific research claims that the chicken came into existence first. Why because the egg of a chicken is made up calcium carbonate and one other protein known as ovocleidin-17. This type of protein is only found in chickens. So with that, the chicken will definitely have to come first in order to produce the egg.
Above are the two scientific view on egg and chicken which one came first. Both scientific views are strong and accurate. Which still makes the riddle unsolved.

In the aspects of human believes, it the chicken that came first. Simply because God created animals to reproduce not eggs to germinate into animals.

In conclusion, there isn't a clear prove to this mysterious question yet. Because even in the scientific point of view there are two different proves to the question. This makes this riddle still unsolved.

I invite @five5 , @mewow and @kodua to this amazing contest. Thank you all for your time. Stay safe.
