The Omphalos hypothesis was named after the title of an 1857 book, Omphalos by Philip Henry Gosse, in which Gosse argued that in order for the world to be "functional", God must have created the Earth with mountains and canyons, trees with growth rings, Adam and Eve with hair, fingernails, and navels (omphalos is Greek for "navel"), and that therefore no evidence that we can see of the presumed age of the earth and universe can be taken as reliable. The idea has seen some revival in the 20th century by some creationists,^[who?] who have extended the argument to light that appears to originate in far-off stars and galaxies^{[not verified in body]} (although other creationists reject this explanation). Many creationists believe that Adam and Eve had no navels, and that the trees in the Garden of Eden had no growth rings.

Chateaubriand wrote in his 1802 book, Génie du christianisme (Part I Book IV Chapter V): "God might have created, and doubtless did create, the world with all the marks of antiquity and completeness which it now exhibits." Rabbi Dovid Gottlieb supports a similar position, arguing further that the evidence for an old universe is strong: "The bones, artifacts, partially decayed radium, potassium-argon, uranium, the red-shifted light from space, etc.– all of it points to a greater age which nevertheless is not true."

Katheryn Elizabeth Hudson (born October 25, 1984), known by her stage name Katy Perry, is an American singer, songwriter and actress. Perry grew up with gospel music, and during her first year of high school she pursued a music career as Katy Hudson, releasing her first studio album called Katy Hudson which failed to chart. She recorded a solo album later, which was never released. After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry.

She first gained recognition with the release of her first mainstream album, One of the Boys in 2008, which spawned three Billboard Hot 100 top-ten songs—"I Kissed A Girl", "Hot n Cold" and "Waking Up In Vegas". Perry supported the album with her Hello Katy Tour. In 2010, her third studio album, Teenage Dream (2010), which topped the Billboard 200 chart, and spawned five number one singles—"California Gurls", "Teenage Dream", "Firework", "E.T." and "Last Friday Night (T.G.I.F.)"—Teenage Dream was the only album (after Michael Jackson's Bad)—to do so, and the first female in history to achieve this milestone. She embarked on the California Dreams Tour, which grossed nearly $60 million worldwide. Perry re-released the album under the name of Teenage Dream: The Complete Confection on March 26, 2012, and the re-release has already spawned the number-one single "Part of Me".
