Naw, I will settle for some disputes as to exactly when the Cambrian began
in various places, especially when the boundary is conformable or
paraconformable, and argue for a single creation event for metazoa. I will
leave the question of the Precambrian life forms open for the time being.

It is good science for precisely this reason to hold their feet to the
fire. Pushing the uncertainty this issue produces into the forefront of
the scientific community will have precisely the effect of making better
science and giving us more certainty in our answers. That is all I want
from pushing the issue.
