Jupitarans:
Jupitarans originate from a terraformed Io and were placed there by the Anunnaki. Apes and primates were actually a species native to Titan and were nearly identical to Jupitarans, though they lacked the intelligence. When Jupitarans left for Earth, they melded their DNA with the primates and even took some of them with them and erased their memories, even committing mask Jupitaran genocide as not to allow the virus that killed ¾ of the population to spread and infect earth. (The Jupitarans were not interested in engaging with the Martians due to the fact that they viewed them as an inferior and very technologically disadvantaged race). This resulted in the creation of Humans. Earth, at the time that Jupitarans were created, was still cooling down. To aid in the process of giving Earth enough mass to support an atmosphere, The Anunnaki threw a sister planet at Earth, the debris or which created the moon (The sister planet was Theia, though Earth didn’t take forever to cool down thanks to intervention by The Annunaki). By the time that Jupitarans were born, earth had cooled but was a desolate waste land with almost no atmosphere, no liquid water, no vegetation of any kind, and no ability to support life. However, The Jupitarans, not wanting to associate with the Martians and not wanting to risk Venus, chose to terraform Earth and planted a small cube the size of Texas full of flora and fauna called “The Garden of Eden" on the planet.
