Hm - good question.\n\nI think the myth of an optimum political-economic system would probably be a stronger contender (at least in the developed world).\nThe myth of progress (ie. that "progress" is always a good thing) is another likely one.\n\nOn a mythos (rather than philosophical) level, the Star Wars films are probably the great global myth of our time (kids in all kinds of countries/languages know all the details - far more intensely than they know about any version of God).\n\nGod was probably the most important myth of previous times, but hasn't been for a while. Another good question might be "When did God cease being the most important myth?"\nSome time between the Enlightenment and the French Revolution?
