Hello everyone.(inspired by carl sagan)

                  1. THE BEGINNING OF BEINGS

We live on a planet which orbits around a star called sun.where our species have got so extraordinarily smart and genius that almost my thoughts are right now being reaching to you with a speed of light...we can look at this as a telypathy of thoughts,where just by a right combination of metals and plastic and glass i transfer my thoughts to you within a fraction of second..

Now lets go back a time where our species  or any other species  didnt even exist..nor did our planet. A time of 15 to 20 billions of years back.if you think twice you could just imagine how long 1000yrs is and multiply it by 10 with a numbers of zeros ahead.

What was happening back then was , the incident  where all the basic elementary particles like quarks and protons and electrons were closely compact with each other very very close just to fit at a single point of a size as of the tip of a needle.

Now these particles had a properties  of its own like proton with a mass and postitive charge ...electron with no mass but a negative charge. With a sudden blast these particles reacted with each other to form possible combination of tremondous         amount of hydrogen and helium. Which were the first elements and most abundant element formed at the beginning  of the big bang. Now this was like a 20 billions of years ago. And the univers was filled with hot gas of hydrogen mostly . Gradually these particles in vaccum started to gather together with the force of gravity..gravity is often called as the hero and villan of our universe which is responsible for  almost all the processes happening in the universe. Back to the stage of universe filled with hydrogen clouds they began to react with each other by fusion  reaction at very hot tempratures . Where hydrogen combined to form helium which later combined to form other few basic elements as carbon oxygen

etc... . This process made many bodies in universe such as planets comets ,even stars were formed by hydrogen  rich atmosphere. Stars consist of hydrogen on its outer layer which combines with fusion reaction to produce heavier  elements. And these elements  being heavier became  the underlayer of outer layer  ..the reaction continued  to form very heavier elements such as platinum, gold , and lead (heaviest stable element) in the core of a star. The stars fusion reaction produced energy which lead a star to expand  but gravity pulled them to form a stable star which would  live for a millions of years uptil its exhaustion of hydrogen fuel. Such stars were formed in all galaxy. But by a chance or so a star called Sun formed in the galaxy of milkyway which attracted hot planets one of them is our own planet. Earth was formed with various elements .these elements were nothing but those formed  inside the stars coreand when the star exploded these elements were released in the cosmos...so the gold you have with you was probably once at a core of some star..not even that you yourself are made by the elements which were once inside in the core of stars..

Now that  we are all made of stars we still depend on them today..how? Now just imagine How the fusion reaction on sun produces  energy as byproduct. This energy of photons,and ultraviolet and infrared and microwaves travel a distance of crores of miles to the earth where they are absorbed by the chlorophylls in the lamina of leaves .and this energy  from sun is converted  to chemical energy ,and stored in plants ..now we eat the same chemical energy and this same energy is converted into electrical energy to run my neural network and allow me to think...so still the sun being so far takes care of us as a father and earth being our mother...

Now before we were even born the earth was not the same as we know it. There were volcanoes  and tsunamis  and thunderstorms etc. Which created more and more complex molecules at a time when no life was present on earth...these processes continued  to form more and more complex molecules to once magically and by chance form a very very complex molecule which had the ability of replicating itself by using resources  and energy around. This was one of those moment which was the classic turning  moment in the history of the earth. This  substace was so complex that it had more atoms than total stars in the galaxies. Today we call it 'RNA' ,composed of nitrogen or perhaps nucleic acids. This is what we call the "BEGINNING  OF  LIFE ON EARTH".
