EARTH……..
As far as we know it's the only home to life in the universe.
WHY??
What is it that makes our planet so special? The answers are hidden deep in the earth's past.
To find them we must travel back in time to see the first human’s walk the EARTH...
To ride continents on a collision course……
Face killer Dinosaurs………
Dive into oceans full of bizarre life forms………
Feel the bitter chill of global ice ages and experience the fury of cosmic missile attacks…………

We must travel back in time until we reach the birth of the earth itself…Then we can piece together our planet’s incredible story and Discover why all of this, all of us ARE HERE!!!!!!!
Our journey starts almost 5 billion years ago, but this can't be right. There is no sign of our beautiful blue planet. Just a newborn star OUR SUN surrounded by all dust. We have arrived too early before the earth has even formed.
Speed up time and we can see gravity pull the dust into tiny rocks. It hardly seems possible. But something as complex as a planet is made from nothing more than dust and rocks. Over millions of years gravity pulls these rocks together to form the earth. One of at least a hundred planets circling the Sun.
But 4.54 billion years ago our planet looks more like hell than home. Up close the temperature is over 1200 degree Celsius. There is no air, just carbon dioxide, nitrogen and water vapour. It's so hot, so toxic that if we got any closer we'd be incinerated and suffocated in SECONDS. The new born planet is a bowling ball of liquid Rock. There are virtually no solid surface, just an endless ocean of lava.

A young planet called Theia is heading straight for us. It's the size of Mars and its travelling at nearly 15 km per second, 20 times faster than a bullet. The intruder’s gravity is distorting the Earth’s surface. And with their collision the blastwave races out around the planet. It’s as though both young planets turn to liquid, trillions of tons of debris blast out into space.

But over the course of just A Thousand Years, Gravity works its magic and turns the rubble into a ring of Red-Hot dust and rock that circles the earth. And now from this ring of all forms over 3000 km ride, we are close to the birth of our MOON.
The sun rises over cooling Earth and sets just 3 hours after Advisors. The impact has set the earth spinning so fast that an entire day lasts just 6 hours. The days may pass quickly, but the Earth changes slowly.

So till now we have reached at the stage of very primitive earth. We have to long way to go....
