Solomon recaps the book of Exodus for us, except in his version, the Israelites worshipped some stupid serpents and god sent wild animals to kill them. These particular beasts have sparkle eyes. Best line of the chapter: For thou lovest all the things that are, and abhorrest nothing which thou hast made: fo never wouldest thou have made anyt hing, if thou hadst hated it (v. 24). It's quite clear Solomon has never actually read Exodus, in which god kills the first-born children of the Egyptians, which I believe he created in Genesis.
Things heathens do: witchcraft, wicked sacrifices (v. 2), child murde, cannibalism, feasts of blood (v. 3), killing souls. And god's punishment: wasps. It didn't work, at least not at first, because it was a naughty generation (v. 10). But in the end, they'll get what they deserve.
People are vain and don't know that god exists. They think the things around them were caused by fire, wind, the stars or water, and think those things are the real god. They're closer, at least.
Other people go looking for god in things of beauty, like gold, silver, jewels, art or antiques. A carpenter cuts down a tree, carves it into a jug, which he then sells, and uses the proceeds to buy himself a nice meal. Then he takes the bits of wood that he rejected for the jug and carves a sculpture of a man, or some vile beast (v. 14), whatever. Then he paints it red. Then he sets up a shrine in a room and nails his figurine to the wall. Then he prays to it. That's about right.
