Today, some seem to take it as not simply possible, but certain that life originated from nonliving matter. Is this justified by the evidence? Let's debate that.
I'd like to begin with a brief criticism of a popular interpretation of one origin-of-life scenario. I've heard some cite the Miller-Urey experiment as evidence that life could form from nonliving matter, but this is an exaggeration. Starting with water, methane, ammonia, and hydrogen, the experiment was able to produce some amino acids. I am not impressed by this because, first of all, it takes multiple amino acids to make a protein, and multiple proteins to make a cellular mechanism (which is only part of a cell).
That, of course, misses an even more fundamental problem with the experiment: the experiment was designed so the amino acids were removed from the environment in which they were formed. Just look at a diagram of the experiment. To put it mildly, this is a poor approximation of a fully natural process, especially if this process is said to have operated continually on the amino acids for millions of years in order to produce living cells.
