Charles Darwin adopted a theory “Survival of the fittest” What he means is not the outer animal but the gene inside the animal which helps the animal to stay longer on Mother Earth by adapting themselves and leaving offspring generation after generation. 

Does crying belong to this earth? Yess! 
If you happen to see an animal on another planet where there is no water then those animals born out of it, will not cry because the water coming out of the body is nothing but it belongs to the chemical availability of the respective planet. We humans cry because Mother Earth is full of water and that water is present in every living being in the form of blood and water. The first one comes out of injury and the second one comes out of emotions.

Why do all mother animals take care of their offspring even by giving their life. It was understood when the gene decided to form a body there was an understanding to safeguard the body in order to survive. These agreements evolved for so many million years before an animal came out of existence. The agreement takes such a long time to understand which cell has to become which one hence there is no confusion once the format is given. 
Suppose, the day the agreement broken i.e. If the mother fails to take care of the offspring then that will be the last appearance of such an animal on Mother Earth.

Why do we believe in God? 
Once you grow up you can see the usage of chemicals and it never changes their properties and ever. This made us believe there is God governing the principle of composition of chemicals intact in order for humans to use it and survive. Suppose, If Gold turned into silver. then the next day it was copper then the human would not have civilized. And would have stayed like other animals.
