The "Big Bang" is decidedly not a theory about the creation of the universe. It describes the (theorised) early moments of this universe's existence.
The evidence is widespread but not conclusive. The theory began when Hubble noted that all galaxies in all directions are moving away from us: the universe is expanding. So the universe yesterday was smaller than today, and the day before was smaller still. If you go back far enough you COULD reach a point where the universe was all stuck together. Rather like if you saw loads of shrapnel spread around stuck in walls (ie had been travelling very fast) you would come to the conclusion that a bomb had gone off.
Now the theory was not (and is still not) universally accepted amongst scientists and a lot of time has been spent trying to decide the issue. The question posed is if the universe had begun very small and suddenly exploded what else would happen? Some of the things that would have happened have been found (the background radiation mentioned in another reply - much the same as the sound of the bomb exploding).
Other parts of the theory, and physics in general, have got problems. One of the biggest is that if we try and measure the size of the universe and relate graitational laws to it there just doesn't seem to be enough "stuff" to make it work. Many scientists have said that there is "dark matter", "stuff" we have difficulty detecting. Others have posited a slightly modified version of Newton's gravitational laws that seems to solve the problem. We wait and see.
Bill Bryson's "A Short History of Nearly Everything" gives a very, very, readable "layman's" guide to all this (and much alse beside)
Stephen Hawkins "A Brief History of Time" gives a much more detailed view of physics and cosmology but its much more technical. If you have a basic scientific education (ie not college level) like me you will understand it up to Newton, get the gist of Einstein and just about catch the odd word or two beyond that!
One word of caution. (I apologise if this was not your intention: but you did post your question in the "Religion & Spirituality" section) Most people believe in a God of Love, a God of Salvation, a creator who made the world and cares for us. This is entirely compatible with modern (and all) scientific thinking. God created the universe - it doesn't say HOW he created the universe (big bang or whatever). I would strongly advise against using current difficulties in physics to try and bolster faith in God, along the lines of:
- Physics can't explain "x": so therefore its God
The problem is that physics can't explain "x" NOW. Physics at the turn of the last century couldn't explain certain things to do with light. If you were alive then you might have said:
- Ha! Physics can't explain how light seems to bend around massive objects: so God exists.
Physics would just have to wait for Einstein to explain it all and your God (yours, not anyone who believes in a God of Love and Salvation) would dissappear in a puff of theotetical physiscs.

To start with, Edwin Hubble in 1927 discovered what we commonly refer to as red-light shift. Its basically the Doppler effect but in starlight.
If a star is moving away from us then the light will tend to stretch out into the red spectrum, if its moving towards us it would shift towards blue. Not only can this be used to accurately tell if stars are moving away, but one can also determine how fast and if they are speeding up or slowing down.
What Hubble found was that almost all stars and galaxies where accelerating away from a common point. This lead to the conclusion that the universe was expanding.
Since we know the universe is expanding that means that it had to start somewhere.
When we look at distant galaxies, millions of light years away, we are really looking at ancient light, it stood to reason that some remnant of the big bang would still be observable and it was predicted that is would be in the form of radio-waves because the electromagnetic radiation had been stretched out into that spectrum. This is exactly what was found... cosmic background radiation, the glow from the birth of the universe. Your can see it yourself on your TV as static.

God has responded 1400 years in the past interior the Holy Quran, financial disaster 21 verse 30 "Did the disbelievers no longer observe that the heavens and the earth have been closed, then We opened them? And We made out of water each and every residing component. could they nevertheless no longer believe?" the main considerable premise of the great Bang concept is that the universe replaced into as quickly as in a incredibly heat and dense state that stronger at as quickly as (a "great Bang"). This rapid enlargement led to the extra youthful universe to relax and led to its contemporary consistently increasing state. great bang concept replaced into proposed purely some many years in the past, yet Allah has printed the fact lots lots earlier that.

You know, on the one hand, I believe that the Big Bang is as big of a crock as that story about that All-Powerful Guy creating it out of nothing in six days.
On the other hand, I wasn't there, so I don't go around preaching my theory like it was a law.

The "big bang" did NOT "create" the universe.
The universe is infinite and our visible universe is a tiny speck in the infinite universe. The "big bang," if it occurred, was an event in the infinite universe and created nothing.

i thought the big bang theory was based off of watching other stars explode...
it's been so long since I learned about the big bang..

Funny thing is, there are Moslims trying to claim the quran testifies to the big bang and science has long since moved on to much more precise theories that rule out just plain "boom and there it was."
I love watching people call their own holy texts wrong.

The background radiation that is uniform and in all directions. The fact that everything is moving away from us at about the same speed.

what is the evidence that"big bang" really happened?it is just another absolutely senseless theory of evolutionist who just want to reject God!!
