TRUTH OF LIFE || WHAT IS LIFE?

Every living thing on this planet is made of cells. A cell is a protein based robot to small to feel or experience anything. It has the properties we just assigned to life. It has a wall from the surroundings creating order so it regulates itself and maintains a constant state. It eats stuff to stay alive, it grows and develops, it reacts to the environment and it creating more of it self. But in all the stuff that makes up a cell, no part is alive.

Stuff in a cell reacts chemically with other stuff forming reactions that start other reactions which starts many other reactions and this chain goes on in order to keep a cell alive. Millions of reactions take place every second in a cell forming a complex orchestra. A cell can build several thousand types of proteins some very simple and some complex micro machines, For eg- driving a car at a speed of 100km/h while constantly rebuilding every single part of it with stuff you collect from the street. That is what cells do but no part of the cell is alive.


Everything is dead matter moved by the laws of the universe so is life the aggregate of all these reactions processes that are taking place? All living things will die. The aim of the process is to prevent this by producing new entities. In other words, this means DNA. Life is a way just a lot of stuff that carries genetic information around. Every living thing faces evolution and the DNA that develops the best living thing around it will stay in the game. So is DNA life? If you take DNA out of is hull, its certainly a very complex molecule but it cannot anything by itself.


So this is where viruses make everything more complicated. They are basically strings of RNA or DNA in a small hull and need cells to do something. Not sure as they count living or dead, and still there are a millions of viruses on earth. There are even viruses that invade dead cells and reanimate them so they can be a host for them, which makes things more complicated. Living thing can evolve into dead things as long as its beneficial. So may be life is information that manages to ensure its continued existence. 


So what is life then? Things,Processes, DNA, information? this is very confusing. The idea that life is fundementally different from non-living things because they contain some non physical element or are governed by different principles than inanimate objects  turns out to be wrong.


If everything in the universe is made of the same stuff, does this mean everything in the universe is dead or that everything in the universe is alive?Does this mean we can never die because we were never alive? What do you thing about life? Write down in the comment section below
