About 100 years ago, scientists discovered that all stars are moving away from each other. By tracking them backwards, they could see that they are all coming from a single location. Exactly what you see if there was an explosion that occurred billions of years ago.
That is almost all the evidence we have. There are theories as to what exploded and what happened just after the explosion.
So the universe has a beginning. The Book of Genesis in the Bible starts with "In the beginning".

Ok, here goes lol.
The big bang was not an explosion, it was an expansion - like blowing up a balloon. No one knows why this happened and it doesnt matter to scientists because anything before the big bang is nonsenseical to them because they can never ever see it. Its a stupid attitude but scientists arent the brightest people.
All the galaxies in the visible universe are moving away from each other as far as we can tell. Which means something must have given enough energy to these galaxes to move them. Galaxies have billions of stars, most several times the size of the sun so it takes a lot of energy to move them.
The creation of the Earth was a completely different event about 9billion years after the big bang. (BB was 13.7billion years ago and the solar system formed about 4.5 billion years ago.)
Basically all particles (protons, neutrons, electrons etc) in the universe have their own gravity and its a fixed amount for each type of particle. When these individual atoms collide they sometimes join together. A single proton is Hydrogen. When two hydrogen particles collide they will form helium.
This will continue until you get iron which is the heavyest material stars alone can make.
Huge stars have to explode to make anything heavier like Uranium.
Anyway, when Iron and other heavy-ish materials are made they really start coming together and over time will form a lump as big as a planet. Stars are just trillions of tons of hydrogen.
Then after the planet cools depending on where it is in the solar system life may form or it may ignite itself into a small star. Jupiter is a failed star that isnt quite heavy enough to form a star.
I think thats what you asked lol.

I'm very glad you asked this question because I now have a much better understanding of what the big bang theory means. Interestingly, one answer referred to Genesis where it says "In the beginning God created the heavens and the earth". I know a lot of people rubbish this saying it's ridiculous to believe in 6 literal days of creation. However, the original Hebrew word used for "day" (yom) can mean a long period of time (not just 24 hours). Each 'day' could have been billions of years.
Also, the heavens and the earth were already in existence when God got to work on forming light, atmosphere, dry land, vegetation and then animal and human life. There is no conflict between scientific evidence to support the age of the planet and the Bible account of how God created life on it. Nowhere in the Bible does it say how old the earth is. The notion that humans have only been around for 6,000 years came from Bishop Joseph Usher who took the names of all the descendants from Adam up to Jesus and guessed at how long they lived then added them all up.

The astronomical evidence of the big bang is compelling, but the philosophical explanation is left wanting. Since you asked in the philosophy section, you probably don't want to hear about the cosmic background radiation, the so-call redshift or doplar effect showing the galaxies expanding away from each other, and other observational data. While they don't 'prove' the Big Bang, they're consistent with that theory.
But getting back to the philosophical explanation, the Big Bang is just one of many inflating bubbles in a spacetime foam. But there is no possibility of getting information from outside our own one bubble. Our egotism can handle only one singularity at a time. To think about what happened prior to the big bang or what will happen at the end of time, is to think beyond our current observational capabilities.

The big bang theory is that in the beginning there was nothing but presumably energy then all of a sudden all the energy that was in this vast place binded together to form an explosion creating a giant mass sending bits flying everywhere across space, stars, planets, comets.

sun and all the stars and planets were one big burning ball of gases. one day it exploded and sun was chipped off a little thus creating 9 planets that started circling around it. now, the best conditions suitable for existance of life were on planet earth. so one day a single celled bacteria joined with another and then another and then another to form a living being. don't klnow what the first living thing was but thats the big bang theory in real easy english.

No I can't.
But if you want to read a book that tells you, don't go to Stephen Hawking's grossly overrated Brief History of Time. The Moment of Creation by Trefil is easier to understand and actually goes into more detail.

god farted ... lol kidding ... i think it had something to do with the sun ... was it a big ball of gas or something? ... i think a couple of asteroids clashed inside it or something and that ignited it
