George, suppose someone says to you that the gaps in the fossil record
exist because God created groups of living things separately and that there
are no fossils to be found in the gaps. This is a typical YEC argument. You
might--at least for the sake of the argument--concede that there are some
"missing links" between groups of fossils. But you would probably add that
those links might be found, and then the "god" of the other person becomes
a bit smaller. You'd be correct. Every time God is invoked to fill in for
our ignorance, and later we find that we really didn't need God for some
supposed gap in our knowledge, our "god" would diminish. Too many
Christians have gone down that road.
In our discussion of human evolution, you seem to depend on as-yet-unknown
mechanisms to link the human race to other hominids. Aren't you falling
into the same trap as the person who invokes God wherever there is a
mystery? That person says our ignornace points to divine action; you seem
to be saying that the fact we are presently ignorant about a gap tells us
some scientific discovery will be made in the future. In the one case,
ignorance is proof that God acts; in the other, ignorance indicates a
mechanism will be found in the future.
I'd rather go back to my original point. Genetic and structural similarity
cannot be proof of descent, given that the organisms are subject to the
same physical laws. There is, of course, no "god of the gaps"; our God is
active in whatever happens. And we simply do not know that mechanisms
presently unknown will be discovered, or are discoverable.
