World governments should prepare a coordinated action plan in case
Earth is contacted by aliens, according to scientists.
They argue that a branch of the UN must be given responsibility
for "supra-Earth affairs" and formulate a plan for how to deal
with extraterrestrials, should they appear.
The comments are part of an extraterrestrial-themed edition of the
Philosophical Transactions of the Royal Society A published today.
In it, scientists examine all aspects of the search for
extraterrestrial life, from astronomy and biology to the political
and religious fall-out that would result from alien contact.
"Will a suitable process based on expert advice from proper and
responsible scientists arise at all, or will interests of power
and opportunism more probably set the scene?" asked Prof John
Zarnecki of the Open University and Dr Martin Dominik of the
University of St Andrews in the introductory paper. "A lack of
coordination can be avoided by creating an overarching framework
in a truly global effort governed by an international politically
legitimated body." They argue that the UN has a ready-made
mechanism for such a forum in its Committee on the Peaceful Uses
of Outer Space (Copuos).
Member states of Copuos should put "supra-Earth affairs" on their
agenda, say Zarnecki and Dominik, and establish structures similar
to those proposed for dealing with threats from near-Earth
objects, such as asteroids, that might be on a collision course
with our planet.
According to Simon Conway Morris, a professor of evolutionary
palaeobiology at Cambridge University, anyone planning for alien
contact should prepare for the worst.
Evolution on alien worlds, he said, is likely to be Darwinian in
nature. He argues that life anywhere else in the universe will
therefore probably have important similarities with life on Earth
– especially if it comes from Earth-like worlds that have similar
biological molecules to ours. That means ET might resemble us,
warts and all, with our tendencies towards violence and
exploitation.
"Why should we 'prepare for the worst'? First, if intelligent
aliens exist, they will look just like us, and given our far from
glorious history, this should give us pause for thought," wrote
Morris in the journal's special issue.
Ted Peters, a professor of systematic theology at the Pacific
Lutheran Theological Seminary in California, considered what might
happen to the world's religions in the event of ET making contact.
Conventional wisdom suggests that terrestrial religion would
collapse if the existence of extraterrestrial intelligence (ETI)
were confirmed, he wrote.
"Because our religious traditions formulated their key beliefs
within an ancient world view now out of date, would shocking new
knowledge dislodge our pre-modern dogmas? Are religious believers
Earth-centric, so that contact with ET would de-centre and
marginalise our sense of self-importance? Do our traditional
religions rank us human beings on top of life's hierarchy, so if
we meet ETI who are smarter than us will we lose our superior
rank? If we are created in God's image, as the biblical traditions
teach, will we have to share that divine image with our new
neighbours?"
His conclusion, however, is that faith in Earth's major religions
would survive intact. "Theologians will not find themselves out of
a job. In fact, theologians might relish the new challenges to
reformulate classical religious commitments in light of the new
and wider vision of God's creation."
"Traditional theologians must then become astrotheologians ...What
I forecast is this: contact with extraterrestrial intelligence
will expand the existing religious vision that all of creation –
including the 13.7bn year history of the universe replete with all
of God's creatures – is the gift of a loving and gracious God," he
speculated.
