The Catholic Church says that human are co-creators with God.
To human beings God even gives the power of freely sharing in his providence by entrusting them with the responsibility of “subduing” the earth and having dominion over it. God thus enables men to be intelligent and free causes in order to complete the work of creation, to perfect its harmony for their own good and that of their neighbors. Though often unconscious collaborators with God’s will, they can also enter deliberately into the divine plan by their actions, their prayers, and their sufferings. They then fully become “God’s fellow workers” and co-workers for his kingdom. (Catechism of the Catholic Church, paragraph 307)
