Which comes first, egg or hen??

The debate has been going on for 2000 years. The eggs have arrived before or before the chickens? A group of researchers from Austolia and France have claimed that they have found the answer. It is assumed that ancient Greek philosophers put the first question. They said that the chickens have come first in the world, then the eggs. Someone said that before the eggs came, then chicken was born from it. Astronomers at the University of Queensland in Austolan and the Neil Institute of France claim that any of the eggs or chickens on the earth It may come before. A research article published on this topic was published on Friday in Physical Review Letters of the State.
