--- I think not. The key here is the evolution makes the prediction
(i.e. makes a statement IN ADVANCE as to what will happen). The creationist
examines the observation AFTER THE FACT. This is the difference between
science and religion.
Evolution is indeed VERY testable, as we can make predictions in advance,
and then see if our predicitons hold.
However, if we follow John's line of thougth, gravity is only a THEORY,
not a fact. We can never see gravity (have you ever seen lines of force
between objects?), we only see the CONSEQUENCES of gravity. Likewise, how
do we know that gravity works on other stars? Or even on the moon (before
we got there)? We believe gravity is a fact because each time we test
its predictions they hold true. The same is correct for evolution.
