Evolution is just a theory,Um, gravity is a law not a theory. I guess there is some argument around the precise meanings of theory and law and the difference between them and whether or not they represent a hierarchy. If those in the field of science could clarify and help me understand the difference better I would appreciate it.
. . . kind of like gravity!
But this still seems like an odd thing to put on a bumper sticker. And really, can we stop shouting at each other and claiming "the other side", whichever it may be on any given argument, are all stupid with bumper stickers? They tend to aggravate and annoy rather than inform and persuade.
