Throughout history, our definition of 'life' reflects our assumptions
about how the Universe works – and why we ask the question. The ways different
human cultures, ancient and current, have talked about life provide some sense
of how we have defined life, and illustrate the aspects of life that fascinate
us. Many cultures used life as an analog to explain the movement of winds and
currents, or the motions of the planets. Today we use those mechanical systems
as analogs for life. Ultimately, we may not really know what life is until we
have discovered more than one independent example of it on places other than
Earth – we need many diverse examples before we can generalize. But without a
definition of what we're looking for, and why we're looking, we may have a hard
time recognizing life when we find it.[Video 1]
