I wrote yesterday about the inadequacy of the evolutoinary process to explain the development and complexity of life we observe. Theistic evolutionists accept the proposition that the natural processes are adequate to explain this. In practice, theistic evolution is a naturalistic view of the origins of life. TE does allow for other miraculous events and God's sustaining power, but not God's intervention for creative purposes once the natural process has begun. In an artice today by Darrell Falk, president of The Biologos Foundation, he states this clearly:
Thus, we should not assume with certainty that God would choose to use supernatural flurries of activity if his ongoing regular activity—that described through natural laws—would accomplish the same end, albeit over a longer period of time. [emphasis added]
This is the crux. For theistic evolution to succeed as an explanation, the natural processes have to be fully adequate to explain the development of the universe after the beginning without God's supernatural intervention. And the evidence just isn't there.
