One of the historical arguments against the existence of God was that something cannot come from nothing, and the idea of God creating living matter from non-living matter (“dust of the earth”) was “illogical”. The problem with “logical” arguments is that they also presume that all the facts are in play when often they are not. The problem is that we don’t know what we don’t know.
That logical argument isn’t heard much anymore because science now postulates just that, that life arose from inanimate matter. Sort of “something from nothing”. The problem of not knowing what we don’t know is alive and active here, especially when we try to define “life” from a scientific perspective. Our categories and definitions in this area are always subject to change as we learn more. It is often only in retrospect that we realize what we didn’t know previously, and what was seemingly illogical is suddenly made logical.
In the debate between creationists and evolutionists the origin of life is often ceded as either beyond the realm of science or not within the purview of evolution. But that isn’t true; science can look at the very beginning of life because we have the ability to look at natural processes and the intelligence to understand how it could have happened. The problem is often one of defining exactly what we mean by “life”.
Mike Haubrich at Clashing Culture discusses the definition problem:
Abiogenesis [the rise of life] is not limited by nature to a single event, it is limited by our ability to clearly define life. The more that investigators learn about early replicators, the more they understand how complex the definition has to be.
He does a great job of discussing this issue. He was inspired by a Panda’s Thumb article by Nick Matzke that clarifies what we do know about the origin of life:
All known life can be traced back to a single common ancestor which, compared to what most people think of as present-day life (i.e. plants and animals), was relatively simple – microscopic, single-celled, perhaps as complex as an average bacterium or perhaps somewhat less so.
Because a lot of creationists, and sometimes others, are a bit thick in the head on correctly understanding this point, let me bash away at some common misconceptions. The phrase “single common ancestor” does not, and never has for people who were paying close attention, referred to a literal single individual organism. Think about a phylogenetic tree with humans and chimps on the branches. When you trace the tree back to the “common ancestor” of chimps and humans, does that node represent a literal single individual? No, of course not! Everyone (well, everyone paying attention) realizes that that ancestral node represents a species or population sharing genes in a gene pool. Ditto for all of the other ancestral nodes in a phylogenetic tree, including the Last Common Ancestor of known life.
More good stuff there.
The Christian shouldn’t have a problem understanding that we may not know what we don’t know; faith itself is defined in ways that show there are things we don’t understand. But the Christian need not stop there; while there are things that will only be revealed to us when we depart from the physical world, God has opened all of creation to our inquiry, without restriction.
Both creationists and evolutionists often claim that the origin of life is outside the purview of evolution. But I think that takes too narrow a view of evolution, decoupling it from the rest of the sciences and our understanding of the universe. Evolution is not a stand-alone theory, wholly independent from the rest of the sciences; it forms a link or two in the chain of our understanding of the universe. That understanding requires many different disciplines, including astronomy, biology, cosmology, and geology to name just a few.
Because the rise of life undeniably happened in the physical world, it is within the scope of science to understand it. Saying science doesn’t have all the answers begs the question; it should be rephrased to add the all important qualifier at the end: “Science doesn’t have all the answers yet.
We know we don’t know some things. When we learn those things, we may find other gaps in our knowledge we haven’t anticipated. In life, in science, and in faith, we often don’t know what we don’t know. Yet.
Faith, Politics, Science
