Secular evolutionists must oppose creation ministries because, if what we are saying is right (and it is)--that God is Creator--then their whole philosophy is destroyed. The basis for their philosophy decrees there is no God. If evolution is not true, the only alternative is creation. That is why they will cling to the evolutionary philosophy even if the evidence is totally contradictory. It is really a spiritual question.
