I'd start a religion centered around worshiping a pantheon of deities. The deities would be represented in symbolic animal form. Worship would consist entirely of building new and more elaborate animal god-themed puzzles, then moving on. After people found our glorious puzzles the faith would grow exponentially. Eventually our flock (literal and figurative) would cover the earth in countless arbitrary temples and over-complex ruins.
The twist is, though, that we'd only choose the absolute shittest of animals to represent our gods.
