Listen to the Big Bang Theory theme song by Barenaked ladies, it says it all!

The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.
Because current instruments don't allow astronomers to peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical formulas and models. Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background.
While the majority of the astronomical community accepts the theory, there are some theorists who have alternative explanations besides the Big Bang — such as eternal inflation or an oscillating universe.
The phrase "Big Bang Theory" has been popular among astrophysicists for decades, but it hit the mainstream in 2007 when a comedy show with the same name premiered on CBS. The show follows the home and academic life of several researchers (including an astrophysicist).

All that we see today, nearly 14 billion years ago (relative to our sources of reference) was all clumped together at a point of infinite density, called the initial singularity.
From this point time came into existence, or to say even if it existed before this, it won't have any effect to our notion of time. Within a millionth part of a second the universe, that is the space time fabric itself, started to expand, there was just energy in the universe.
Quantum fluctuations took place, photons were emitted, particles and antiparticles popped into existence and annihilated.
Gravity separated out from the other three forces. During this time somehow particles won over their counterparts and a majority of them established their ascendancy. Quarks clumped together, gave rise to neutron and protons, with further combined with leptons to form Hydrogen atoms. A lot of time elapsed since without any major change, when the universe gained an appropriate temperature, matter started to clump together by their gravity. Hydrogen atoms together fused into helium and other heavy elements and formed stars.
Our solar system was formed from the gravitational collapse of dust and gas cloud about 5 billion years ago, which further with its spin collapsed to form our sun at the centre in a supernova.
The dust surrounding the sun, which comprised mostly rock like particles clumped together under gravity and formed planets, that's how our Earth was born.
