Yes, it's now pretty sure that the early atmosphere was not as chemically reduced as Miller and Urey thought 50 years ago - nitrogen instead of ammonia, and carbon dioxide instead of methane. Of course, Miller and others have conducted experiments on these mixtures, and still can get "biomolecules" to form in several different ways. Add in the fact that things as complex as the vitamin niacin have been found in the interior of pristine meteorites, and it doesn't leave all that much room for saying Miller and Urey promoted "a lie." Their initial experiment was probably in error - wrong starting materials for Earth - but it pointed the way to a lot of fruitful research.
Like iron, the amino acids created by the first miller experiment never fulfilled all the requirements of living.
We all know that.
If there is a biology text anywhere that claims otherwise (and you have failed to produce one) it is wrong, and inexcusably so. Do you have a point here at all, JF?
