Creation - Egg first? or Hen first?

Which was created first? Is it the egg or the hen? How such a big banyan tree comes out of very small seed?

An atom when placed in a good atmosphere becomes good seed and when it gets some moisture and depending upon the nature of the soil it grows into a banyan tree.

The same atom in a poisonous atmosphere turn out to be a poisonous plant.

Neither the egg nor the hen came first. Just as a man’s mind accepts good and bad things the atoms which come and strike the earth make the egg and then naturally then the hen comes out of the egg.

This is the state of all sorts of atoms.
