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.
