The Earth is an amazing place. It provides everything needed to sustain
billions of creatures, plants and human civilization. We owe our very
existence today to the planet's turbulent past. Our world was formed by
a series of cataclysms, from the most powerful blast in the Universe to
a planetary collision that could have destroyed it. Yet without these events,
the Earth would not exist. Nor we. Could the same extraordinary chain of
events have created other earth-like planets elsewhere in the Universe?
Inhabited by creatures like us? The odds seem slim. But the incredible
story of the birth of our world reveals that earths must be abundant.
The question is no longer "are we alone" but "how far away are our neighbors?"
