London, Aug 5 : British professor Paul Davies has claimed that the
best place to look for messages from aliens is not in space, but
inside our own bodies.

Davies was quoted by NewScientist as saying, "that our DNA is the
right place to look for a coded message from aliens," and believes
that the cosmic greetings could have been planted into human bodies
with the help of a virus.

Yeah, DNA travels faster than light.
