From Dawkins book
"The combination lock on my bicycle has 4,096 different positions. Every one of these is equally 'improbable' in the sense that, if you spin the wheels at random, every one of the 4,096 positions is equally unlikely to turn up. I can spin the wheels at random, look at whatever number is displayed and exclaim with hindsight: 'How amazing ...[text shortened]... at not only allows for
the proper combination but also allow it to flourish too.

Your point being, and correct me if I'm wrong here, that for life to form on earth it would require the right materials in the right quantities at the right time. These don't seem to be particularly difficult conditions to fulfil considering this ambition was undertaken in 1953 by Messrs Miller and Urey and after only a week saw amino acids form, the building blocks of protein.
This result is made all the more astonishing by the crudeness of the experiment. If it was this easy to generate the building blocks of nucleic acids, sugars, lipids, and amino acids in a laboratory with only water, methane, ammonia, hydrogen, and some electricity then why is it so hard to imagine life forming from a much more complex system?
Finally, earth was a lot less hospitable in its early history and only after many millions of years did plants produce sufficient oxygen enabling more complex species to evolve. Life didn't develop in an ideal environment but rather created one.

Originally posted by KellyJay"We found one" being a figure of speech for "life appeared". It's not strictly speaking a combination lock either, you know.
You found one? I don't think so, you may say there is life here, but
beyond that the question is how did it get here.

yet even with intent, put forward a means to build life from completely
non-living material? You want to suggest it can happen just because
you see amino acids that were both right and left handed?

Do you deny that small changes can become significant? If so, present an argument.(not a strawman).
If you do agree with it, ...[text shortened]... icant a change is possible and how significant a change is not possible and what the barrier is.[/b]
Unlike the card trick where we can figure out how many possible out
comes there are in a card deck once we suffle them, then say "Wow,
we beat the odds after we suffle them because they are in some
order!" That is not the same thing as saying, I'm going to suffle them
and predict all 52 cards in the order they are going to be in, and get it
right. Having life already here is 1/1 we can see we are living
creatures ourselves, but that does not mean that because of that it
automatically means life just sprang from non-life and grow into the
variety we see today over time. Suggesting it is not only likely but the
only likely way is a belief on your part or anyone else' who makes
such a claim.

Pay special attention to the words "controlled" and "experiment" and then juxtapose those words with such phrases as "hostile environment" and etc. Within a very short amount of time, the significance should be clear.
The scientific method requires the experiment to be controlled. Your conditions for the validity of an experiment seem to be that they should exactly replicate the environment which they represent. I don't think Miller or Urey had a spare earth, billions of years old, out back.

Originally posted by Green PaladinI don't "see" the phrase; the most rudimentary understanding of the primordial soup's supposed state should suffice in providing that level of clarity.

Apart from being a completely biased view (there are no problems listed only evidence), there is a representation of the Creation of Adam, painted by the screaming queen, Michelangelo!

The Urey-Millar expt could not be conducted nowadays except in controlled conditions - the environment is too oxidising due to all the plants pumping out oxygen and the system would quickly be overrun with bacteria anyway - both things which wouldn't have happened 4 billion years ago.

You know all this though Kelly.
