Each time a mass extinction occurred, life found a way to come back from the brink. Since we can only measure as far back in time as we had solid rock on this planet, we are limited in how we can measure the real age of the earth. A number of political and military leaders, among them Odaenathus, Aurelian, and Diocletian attempted to keep the territory of the Empire intact, while a number of Germanic tribes and the newly formed Sassanid Empire attacked it relentlessly. This video was narrated by our good friend Officially Devin. Life has tenaciously clung to this small blue planet for the last three billion years.

Check out his channel, he has some of the best Total War machinimas ever created: We also have a few other projects in English: Scientists are still trying to unravel one of the greatest mysteries of earth: Then an unprecedented profusion of life in incredibly complex forms began to fill the oceans. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. A number of political and military leaders, among them Odaenathus, Aurelian, and Diocletian attempted to keep the territory of the Empire intact, while a number of Germanic tribes and the newly formed Sassanid Empire attacked it relentlessly. So the age is a theoretical age. In the infancy of our home planet the entire earth was molten rock - a magma ocean. When Did Life on Earth Begin? Narrated by Brian Cox. Perhaps we've been getting periodically belted by more space rocks ie. When did "life" first appear and how did it happen? Scientists have been looking increasingly to space to explain these mass extinctions that have been happening almost like clockwork since the beginning of "living" time. The continual changing and reshaping of the earth's surface that involves the melting down and reconstructing of old rock has pretty much eliminated most of the original rocks that came with earth when it was newly formed. As the cooling continued, water vapor began to escape and condense in the earth's early atmosphere. As the collisions tapered off the earth began to cool, forming a thin crust on its surface. Clouds formed and storms raged, raining more and more water down on the primitive earth, cooling the surface further until it was flooded with water, forming the seas. Each time a mass extinction occurred, life found a way to come back from the brink. Russian Art in the 20th Century — http: Check out his channel for some kick-ass Let's Plays. It is theorized that the true age of the earth is about 4. The oldest rocks geologists have been able to find are 3. Economic crisis, internal strifes and foreign incursions continued for decades, while around 50 emperors and pretenders competed for the throne. Since we can only measure as far back in time as we had solid rock on this planet, we are limited in how we can measure the real age of the earth. Scientists are finding new cues as to how life first began on earth in some really interesting places - the deep ocean.
