Could Aliens Have Created Life On Earth?
By Annalee Newitz

We know a lot about the history of life on Earth, but how it
began is still one of our greatest scientific mysteries. One
hypothesis is that life actually originated on another planet,
and many scientists today take the idea quite seriously. Though
it sounds like the plot from recent scifi movie Prometheus, it's
an old idea that even the celebrated nineteenth century
physicist Lord Kelvin and Nobel winning geneticist Francis Crick
have advocated. That's right =97 the evolution of life might have
its beginnings on another planet.

Over 120 years ago, Kelvin shocked the British scientific
community in a speech about what he called "panspermia," where
he suggested that life might have come from planets smashing
into each other and sending bits of life hurtling through space.
He and a few colleagues had hit upon this notion after observing
the massive 1880 eruption of a volcano on Krakatoa. To be more
precise, they observed the aftermath of the volcano, which
completely sterilized the island. No life was left at all. But
then, within months, seedlings began to sprout and life took
hold again.

Where had that life come from? To naturalists of the nineteenth
century, it was obvious that it had drifted there from nearby
islands. Seeds and insects blown on the wind, or floating on the
tides, had begun the process of re-greening the stricken
landscape. This got Kelvin thinking about the origin of life on
Earth. Couldn't the same thing happen to barren planets drifting
in space? Perhaps life had drifted to Earth on the stellar
