Sometimes called the Human Era, this is the history of Old Earth's civilizations before the advent of interplanetary technologies. It is exclusively the story of the rise of baseline humanity, the clade that gave rise by one means or another to all subsequent Terragens, and of humanity's eventual dominance over the other species on the planet. Baseline humans have been eclipsed since by their human nearbaseline descendants and by the various nonhuman clades, not to mention by the transapients, but they set the pattern of events for the millennia to follow across a radius of thousands of light years.

- Chandrasekhar, Subrahmanyan - Text by M. Alan Kazlev
Old Earth Indian-American astrophysicist, 59 BT - 26 AT (1910 -1995 c.e.), who studied stellar physics, evolution, and black holes. He realized that the fate of dying stars depended upon their mass, and above a certain point (1.4 times Sol mass, known as the "Chandrasekhar limit"), a star will undergo extreme collapse and not simply becomes a white dwarf. There are a number of asteroids, habitats, ships, one black hole, and several black hole observatories named in his honor.
- Copernicus, Nicolaus - Text by M. Alan Kazlev
Old Earth amateur Polish astronomer who developed the Copernican system, a model of the solar system in which all the planets orbit the Sun, thus overturning the earlier Ptolemaic System.

Forerunner of the scientific approach, considered among the great thinkers of Old Earth.
- Einstein, Albert - Text by M. Alan Kazlev
Old Earth late Industrial Age German/American physicist, 90-14 BT (1879-1955 c.e.) and popular su genome template. Formulated the Theories of Special and General Relativity. Einstein won the Nobel Prize in 48 BT (1921 c.e.) for explaining the photoelectric effect.

Like many ancient languages it experiences occasional revivals by retro-abo or neo-whorfian groups.

- Old Earth - Text by M. Alan Kazlev
Generic term used to designate Earth before the Great Expulsion. As well as the literal meaning, and the reference to Terragen origins and ancient baseline history, the term has various other associated nuances, from the ridiculous or exaggerated to the romantic or sublime, including lost paradise, fool's opportunity, pre-archaiocractic human supremacy, unmoderated baseline civilization (positive or negative, depending on context and clade), natural evolution, and so on.
