About 13.5 billion years ago, the universe started out as a singularity (think of all energy and matter compressed into one point at the beginning of time). As time progressed the singularity exploded with a huge burst of energy. This caused rapid expansion of what we know as the universe. It was hot, very hot, but then started to cool as it expanded. As it cooled and expanded, the particles in the original plasma that came out of the explosion started to combine, eventually forming the elements of matter. The matter began to combine into stars and ultimately this lead to the dominance of gravity and the creation of planets.
Consequently, the Universe is still expanding from this original big bang, the matter is continuing to move outward and the distances between the clumps of matter that have formed is getting larger. There was once a theory that the universe would only expand so far and then gravity would take over to make it all collapse on itself, but that theory has now been discarded. It seems the Universe will continue to expand indefinetly, so that eventually, if the earth lasts long enough, the sky will go dark and we would see no stars because they would be too far away.
So it might be reasonable to think of the big bang as like a firework going off up in the sky, all the fragments of the firework explode out from the center and travel away from each other--if there were no gravity or friction, they would continue to travel endlessly and each burning piece would get more distant from every other piece.

The Big Bang Theory is the dominant scientific theory about the origin of the universe. According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions. Although the Big Bang Theory is widely accepted, it probably will never be proved; consequentially, leaving a number of tough, unanswered questions

The space between the galaxies is expanding. Run the clock backwards and everything squishes back into a point. The best way to visualize the big bang is our entire universe is an explosion (although there are people that would say this is missleading since it is not expanding into anything, it is space itself that is expanding).

Okay. Here goes.
Think of all of the matter in the universe compressed ( squished ) together into the smallest dot that you can create with a pencil point, or even smaller. All that matter has a lot of energy in it. That energy can't be contained and explodes, scattering all that matter. Big Bang.

The theory is that at one time, about 15 billion years ago, all matter in the entire universe was located in one spot. It exploded and started to spread out - as the hot gases etc, started to cool, Galaxy's, stars, planets, etc. were formed over long periods of time.

Yah. There was a big boom, and then time unfolded and things cooled down. Time continues to expand in space, and as time passes, things change. Heavier elements than hydrogen is produced and through a wacko coincidence the scourage of the world humans were born

Something exploded years ago and created the earth.
