Omphalism

Omphalism, sometimes called Last Thursdayism, is the notion that the world was created with the appearance of age: that Adam and Eve were created with navels (from the greek "Omphalos"), implying a birth that never occurred, trees with yearly rings, light already on the way from distant galaxies, and so forth.

The main problem with omphalism is epistemological: it can never be disproved. Any given piece of evidence, be it starlight from a distant quasar or just our memories of a time before last Thursday, might be real, or might have been planted by an omnipotent deity.

Another problem is theological: false evidence of age is deception, and must have been planted by a trickster god.
