Birth of the Planet
Sun, Mar 1, 2009 43 mins
30 million years after the birth of the Earth, a cataclysmic collision with a Mars-sized planet almost destroyed the planet completely. Instead, this chance collision formed the moon, triggering an extraordinary sequence of events that formed this unique planet teaming with life. As the vaporized Earth reels from the impact, the moon forms out of the dust and rock debris that gravitate around it. This world is completely inhospitable to life and yet remarkably, within a few billion years, life takes a hold. And all this is possible because of the moon. Mixing Earth's organic rich oceans with giant tides, slowing Earth's rotation and stabilising Earth's axis, the moon plays a vital role in progression of life.
