What is your view on panspermia and the exogenesis hypothesis?
)
August 13th, 2009
From Wikipedia: Panspermia is the hypothesis that “seeds” of life exist already all over the Universe, that life on Earth may have originated through these “seeds”, and that they may deliver or have delivered life to other habitable bodies. The related but distinct idea of exogenesis is a more limited hypothesis that proposes life on Earth was transferred from elsewhere in the Universe but makes no prediction about how widespread it is.
Evidence has accumulated that some bacteria and archaea are more resistant to extreme conditions than previously recognized, and may be able to survive for very long periods of time even in deep space. These extremophiles could possibly travel in a dormant state between environments suitable for ongoing life such as planetary surfaces.

Our human bodies are made of star dust. What about our DNA?
