is that the current objection should not now be, "Your _idea of
creation_ is all wrong," rather than the one which has been strongly
put forward (and against which I am contending), "There is no place for
a Creator."

(5) This is the only other _general_ point that remains to be taken up
in connection with the theory that all living forms are due to the
gradual accumulation of small favourable changes without creative
intervention. The objection is that we cannot obtain the inconceivably
long time required for the process of uncontrolled and unaided
evolution.

I am not here concerned to argue generally for the shortness or longness
of the periods of geological time; let us, for the purposes of argument,
admit a very wide margin of centuries and ages; but _some_ limit there
must be. The sun's light and heat, for one thing, are necessary, and
though the bulk of combustible material in the sun is enormous, there
must be some end to it. Sir William Thomson has calculated (and his
calculations have never been answered) that on purely physical grounds,
the existence of life on the earth must be limited to some such period
as 100 millions of years; and this is far too short for uncontrolled
evolution.

We know from fossils, that species have remained entirely unaltered
since the glacial epochs began, and how many generations are included
even in that! If no change is visible in all that time, how many more
ages must have elapsed before a primitive _Amoeba_ could have developed
into a bird or a Mammal?

In Florida Mr. Agassiz has shown that coral insects exist unchanged,
