A chicken versus an egg which is older and why?

The human understanding is very limited even with all the hypes in every defined ecosystems of ours. Empirically, there are a lot of unknowns within and around us both visible and invisible. This simple question of the "egg and chicken" seniority is torturing our cerebral wherewithal beneath abyss. Depending on the side of the mental prism your are projecting your view from, is either the egg is the senior or the chicken is older. Proof it!   Now, if the chicken is aired as the senior, where did it come from is the universal question still begging for answers. Conversely, if the egg is projected to the first, where did it emanate from? This simple question is now very complex, no scientist, a politician, an archeologist, a biologist etc has a remedy to it as we debate. I guess we have to live with this myth until a smart human or modern machine figure it out. Your thoughts? Welcome to provocativedebate.com.
