DB> Well, now... we see where a particular molecule, which form
DB> is a function of quantum mechanics and sub-atomic physics, is
DB> exhibiting characteristics of 'life', just as predicted by the
DB> computer models of conditions on the primitive earth 4 billion
DB> years ago.
I don't consider anything sub-cellular to be life. In any
case, prions depend on cells for replication. And, it would
help if you told us of one of those computer models...
DB> Because there ain't no free lunch. To develop life as we
DB> have found it so far, demands a chemical activity level of
DB> a high order, such as in a liquid. Venus does not seem to
DB> have any liquid. You also need a power source, either as
DB> light, or a constant supply of new chemical into a given
DB> location. Venusian rock is too inert to respond to the
DB> presence of light.
What's the difference between chemical activity of a high
level and of low level, besides time needed to accomplish
the same thing? And, based on what do you know that the
Earth's chemical level is of a high enough order to account
for life on earth... After all, no one has managed to
produce faverable odds on the formation of life (even if
the whole universe were a hot organic soup).
DB> If life did exist there, I would expect to see it high in
DB> the atmosphere; but that would also depend on some sort
DB> of diurnal change or weather to move molecules from one
DB> kind of condition to another, and the consequent chemical
DB> reactions that might take place.
Based on what? Any math you could show me would still indicate a
virtual impossibility. So, until you find new mechanisms and new
forms of "life" you're not in much of a position to expect life
to more likely be found one place rather than another. You
shouldn't expect to find life any place.
