There are lots of chemists and biologists who think that self-
replicating RNA is a credible step on the path towards evolving
life. There is no need for the seeds of life to have come from
elsewhere than earth, although that possibility is not excluded.

It's remarkable that the reproduction of RNA and DNA still today
can be made to work simply by cycling the temperature of the right
mixture of chemicals, much like day and night cycles, as may well
have happened on a young earth.

To our current knowledge, actual intelligent designers are even
less probable than random mutations producing a working cell. How
did the intelligent designers come to be? They would have been
subject to the same kind of constraints as life on earth, the
right conditions and enough time.

In fact, as long as we haven't found evidence of life elsewhere
in the universe, we can't have any real idea of how common or rare
it is.

partial quote from that site:
 After years of study, in 1997 Dr. Levin concluded that the experiment had, indeed, detected life on the red planet,
 and published his conclusion.
 Subsequent findings of environmental conditions on Mars and research on organisms found in extreme environments on Earth have been consistent with his claim.

 NASA is controlled by republicans and will NEVER be allowed to admit to have found life
