However, there are problems of course.
Some people suggest that the early
Earth's atmosphere was not like
the one in the experiment.
Some people question how much lightning
there was, and whether the correct
amounts of lightning and chemicals could
ever all be in the right place at the
right time.
Finally, some people say, even if you
can produce amino acids on the prebiotic
Earth: So what? Amino acids by themselves
are certainly not life. How do you get
from amino acids to life?
We'll talk about this last question some
in the next couple of weeks.
