Darwinism. Everything came from nothing, and nothing means anything. We're extensions of the scum pond, fighting our way along with other biologics towards eventual extinction.
Whenever a species gains an upper hand, it gorges itself on resources, pillaging its environment until catastrophe.
Kids = selfish and self destructive scum
Creationism is oriented around a Creator God who placed his children here on earth to garden, learn, build and raise other children of God. The Earth is a bountiful, and when humans guide and care for the Earth it is fruitful.
Kids = Children of God
