If you think both systems through, and don't compromise the basic tenets of either of them, they are incompatible.
Most people don't bother, so they accept a mishmash of both sides.......not a total acceptance of evolution, and not a total acceptance of Scripture (even the New Testament).
That's where 'theistic evolutionists' are sitting.........on a wobbly fence.
That is your opinion. I have no issues seeing evolution (which has tons of evidence to back it up) as Gods "design". ID, on the other hand, has no evidence and no validity.
Evolution does not contradict the existence of God.
