A report filed by the Librarian during her time indexing species on the planet led her to believe that the that the Precursors had done experimentation on the planet's native lifeforms due to the mammalian-level intelligence exhibited by certain scyphozoa and cephalopoda at that time of her filing said report.<ref>'''[[Halo: The Flood]]''' (2010), ''Adjunct''</ref>

The remains of a deceased [[Catalog]] unit, and a damaged [[monitor]], which revealed that humanity achieved its earliest known spacefaring technological state prior to [[1,100,000 BCE]] and that Forerunners believed humans had "moved their interstellar civilization outward along the galactic arm" by [[150,000 BCE]]. Not only is the dating for humanity's origin less sure now, but the very idea of Earth has humanity's birthplace has also been revealed to have been a matter of debate for the civilization that preceded and witnessed the [[human-Forerunner wars]] and some Forerunners. That ancient empire had lost many of the records that could have proven or disproven the issue, and human ruins had also been discovered on multiple worlds beside Earth from forgotten eras of prehistory. Regardless of when and how humanity first evolved and developed, it is clear that humans were present on multiple planets over a million years ago, and it was not until thousands of years into this civilization that leading human scientists traced the species' origins to Earth.{{Ref/Reuse|pri238}}
