Philosophy
It hasn't been brought foreword yet, but I'm sure the debate will begin to boil. The preliminary data revealed by Huygens regarding Saturn's largest moon Titan and based on our current perspectives of what it takes for life to originate and prosper, some religions and individuals of the world may begin to become nervous. Claiming exoplanets [candidates for environments for life] exist is one thing, but to have a potentially life giving body in our own backyard is another thing. Some will become offended that man's uniqueness and relationship with God would be tarnished and shake the foundations of faith. If it is granted that a body like Titan could produce and sustain life [even sentient beings in time], then it is quite possible it has happened before, now, or tomorrow anywhere in the universe. [That still doesn't preclude contact.] For some this idea would erode the relationship with God. Frankly, such a situation in no way necessitates any diminished perspective of God. All concepts associated with God may well be honored for all citizens of the universe. It is better for religion/theology to embrace science and modify some of the old tenants. Science is not on a campaign to abolish personal or collective faith, but to enhance. Resistance and rigidity are not really good ideas for science isn't leaving anytime soon and the issues will have to be resolved. Any thoughts about the above. And please, refrain from a religious "soap box" approach by citing religious texts. Titan may well be the first close step to finding a happy ground between religion and science and cease all the bickering.

NASA Press Release:
"During its closest flyby of Saturn's moon Titan on April 16, the
Cassini spacecraft came within 1,027 kilometers (638 miles) of
the moon's surface and found that the outer layer of the thick,
hazy atmosphere is brimming with complex hydrocarbons.
Scientists believe that Titan's atmosphere may be a laboratory
for studying the organic chemistry that preceded life and
provided the building blocks for life on Earth. The role of the
upper atmosphere in this organic "factory" of hydrocarbons is
very intriguing to scientists, especially given the large number
of different hydrocarbons detected by Cassini during the flyby.
Cassini's ion and neutral mass spectrometer detects charged and
neutral particles in the atmosphere. It provides scientists with
valuable information from which to infer the structure, dynamics
and history of Titan's atmosphere. Complex mixtures of
hydrocarbons and carbon-nitrogen compounds were seen throughout the range of masses measured by the Cassini ion and neutral mass spectrometer instrument.
"We are beginning to appreciate the role of the upper atmosphere
in the complex carbon cycle that occurs on Titan," said Dr.
Hunter Waite, principal investigator of the Cassini ion and
neutral mass spectrometer and professor at the University of
Michigan, Ann Arbor. "Ultimately, this information from the
Saturn system will help us determine the origins of organic
matter within the entire solar system."
Hydrocarbons containing as many as seven carbon atoms were
observed, as well as nitrogen-containing hydrocarbons (nitriles).
Titan's atmosphere is composed primarily of nitrogen, followed by
methane, the simplest hydrocarbon. The nitrogen and methane are
expected to form complex hydrocarbons in a process induced by
sunlight or energetic particles from Saturn's magnetosphere.
However, it is surprising to find the plethora of complex
hydrocarbon molecules in the upper reaches of the atmosphere.
Titan is very cold, and complex hydrocarbons would be expected to condense and rain down to the surface.
"Biology on Earth is the primary source of organic production we
are familiar with, but the key question is: what is the ultimate
source of the organics in the solar system?" added Waite.
Interstellar clouds produce abundant quantities of organics,
which are best viewed as the dust and grains incorporated in
comets. This material may have been the source of early organic
compounds on Earth from which life formed. Atmospheres of planets and their satellites in the outer solar system, while containing methane and molecular nitrogen, are largely devoid of oxygen. In this non-oxidizing environment under the action of ultraviolet light from the Sun or energetic particle radiation (from Saturn's magnetosphere in this case), these atmospheres can also produce large quantities of organics, and Titan is the prime example in our solar system. This same process is a possible pathway for formation of complex hydrocarbons on early Earth."
