All the matter in the universe was originally a concentrated lump called primeval atom.Big Bang was an exploison that occured 15 billion
years ago,leading to the formation of galaxies of stars and other heavenly bodies.Since then,all the galaxies have been flying away from one another causing expansion of the universe.

here's your answer looking for
BIG BANG THEORY :-
the big bang theory is the theory that answers the origin of our universe. There are many theories that States and explains the origin of our universe but the big bang theory is considered as a most accurate theory till now.
What is the Big Bang?
BIG BANG is a cosmic inflation that results the formation of our universe. According to the Big Bang Theory, our universe was in singularity that was floating in nothingness. Now what the nothingness means ? :-/
When we talk about nothing else, then our brain thinks emptiness. But nothingness is totally different from emptiness. Basically, nothing else means nothing, even neither the space nor the time. Or in other words we can say that, if there is no dimension that is called or termed as nothingness.
Remember :- Vacuum cannot be considered as the nothingness because the vacuum also have space even the whole universe is interwoven in the space and time filaments.
Now, what's singularity? :-\
singularity is a point where a finite mass get compressed to the zero volume or a point. So, it can be considered as the Zero dimensional point of infinitely dense mass. Here, all laws of Physics cannot exist.
So, before Big Bang our singularity or the whole universe was floating in nothingness.
Now, nobody knows the reason of the sudden incredible cosmic inflation. The singularity starts expanding rapidly and created our own universe. And this incident is only known as the BIG BANG.
When BIG BANG happened? => 13.8 billion year ago.
Now, what was before the big bang?!!!!!!!!!!
Basically, before Big Bang that time was not in existence. So, discussing this matter is just pointless thing.
About a Billionth of a billionth of a Billionth of a second just after the big Ben is called as the cosmic inflation.
At this time the temperature of universe was a hundred millions millions millions millions degree Celsius!!!!!! The initial size of singularity was billionth of size of proton. And it increase its initial size to the 1 centimetre in only 10^-37 secs.
Now, during 10^-35 sec to 10^-32 sec Big Bang over.
Summary of big bang :- the Big Bang was the cosmic inflation by which our universe is still expanding at high rate. 13.8 million year ago our universe was in the zero dimension that is singularity that was floating in the nothingness. The sudden inflation occur that results the formation of our universe.
⭐Evolution of matter :-
The Big bang ended, now our universe start cooling. But is temperature was not still favourable for the formation of matter. So, the particle were still not in existence. Only quark gluon plasma was there. Now, as the time passes our universe get cold enough for the formation of particles. And this results as the formation of quarks and leptons. And in few millionth of second , the quarks formed neutrons and protons . In a min only quarks combined each other to form the nucleus of an atom. Now, our universe get its first atom of Hydrogen.
But, during the formation of particle, there is the formation of antiparticle also. and when they came in contact of each other then, they get converted into electromagnetic radiation (photons) or get annihilated. Now, but if the particle and antiparticle form in the same numbers then they should get annihilate with each other. But , today we can see the matter around us. that means there was asymmetry that for every million of antiparticle there was one extra particle. and this Residue or remind particle we see today as the matter around us.
and because of this annihilation only , today the photons can travel freely in space.
Formation of Cosmic bodies :-
As, the matter was formed then, the gravitational force plays the important role in the formation of stars galaxies planets etc. The area of a energy density region starts attracting the atoms of the gravitational force. and by this attraction of gravitational force our first Nebulae was formed.
these Nebula starts coming nearer to each other and become denser and denser and become highly densed. And buy this the first Star came in existence in which the nuclear fusion was ignited.And after few years these stars form clump and later it becomes galaxies.
But the age of a stars are limited that after after sometime they have to die. And this ends with massive explosions called supernova and this ejects various energy and materials. Later, this material makes the Nebula again. So, this all process continue and form then you start again. Sometimes, some elements starts for me some weird structures that was never formed before. These are nothing but our planets in which nuclear fusion is not ignited yet!!
So, this all was about THE BIG BANG, EVOLUTION OF MATTER and FORMATION OF COSMIC BODIES.
