many factors and enzymes are involved in the clotting process, working in a
chain. For example, there are 16 different elements producing thrombin
alone. For just one of them to be left out of the equation will halt the clotting
process. According to the theory of evolution, one of the countless proteins
involved must have emerged first, with the others then appearing in sequence
over very long periods of time. However, no living thing could afford even
a brief waiting period. Such a system can only function when everything
exists, fully formed. This shows us that these perfect systems are
examples of God's creation.
