>>>Why can’t evolution be part of God?
Because the idea of an intelligent designer — God — makes sense, and plausibly explains mysterious phenomenon like the linguistic code nature of DNA; the idea of small incremental changes from random causes over long periods of time — Darwinian evolution — makes no sense, and requires highly implausible scenarios to explain these same phenomena.
>>>I find it amazing that one cannot be a person of faith AND an adherent of evolution.
On the contrary, Darwinian evolution itself is a kind of religion — the 20th century’s version of a purely materialistic creation myth — and actually requires LOTS of faith.
The Church and most of its adherents used to express the exact same sentiments about planetary matters. Some people who have faith are afraid of science. In the past, that attitude has been counter-productive, to put it mildly.
It is reasonable to disagree on these matters. It is asinine to be certain in these matters, especially for a person of faith.
