Ageoism
Ageoism (from Ancient Greek ἀγεωισμός; ἀ- 'without, lacking', γεω- 'earth') refers to the philosophy or scientific theory that Earth, the original human homeworld, does not exist.
Theory
Ageoism does not deny the fact that a human homeworld exists, rather, it purports that the common belief that the ships of Icnosis came from a now inaccessible region that Earth is located in is flawed. Proponents claim that humans, rather than having originated from billions of light-years away, would have evolved naturally on one of the planets in the Settled Systems.
Criticisms
A large number of scientists offer counter-evidence that demonstrates the missing link between humans (and some domesticated fauna, such as pigs, cows, dogs, cats, and birds) and the wildlife found across the various habitable worlds in the region. A unique feature that is shared by humans and their domesticated animal food sources is the encoding of genetic material using DNA, a function not found in any other living organism in the Settled Systems.
Furthermore, no human ancestor species has been found in any strata of the worlds inhabited by a sizeable human population.
