Rainbows, as far as I know are always above the ground and if more than 6 feet high, usually above peoples' heads. If we can't agree on this, then someone has some serious issues.

Rainbows are an optical phenomenon - like an image in a mirror or like a mirage in the desert. They may have an "apparent" location ("up in the sky", etc.) and an "apparent" size ("all the way from the TransAmerica Building to the Coit Tower"), but in actual fact, they don't exist in a concrete sense and therefore have no "real" location.

You could make the same claim about anything. Science says that even what we call solid, physical objects are actually mostly empty space, and that their apparent solidity is a function of our sense perception.
