[[File:Moon2.jpg|thumbnail|250px|right|"Tidal friction causes the moon to recede from the earth at 4 cm per year. It would have been greater in the past when the moon and earth were closer together. The moon and earth would have been in catastrophic proximity (Roche limit) at less than a quarter of their supposed age."<ref>[http://creation.com/age-of-the-earth Age of the earth]</ref> see: [http://creation.com/the-moon-the-light-that-rules-the-night Recession of the moon from the earth] ]]

# [[Spiral galaxies]] appear to be young, and only implausible proposals of the existence of [[dark matter]] can reconcile the spirals with a belief in an old universe.
