- 500,000 – 40,000 BC: Birth of Man: The Asgardian God Odin plants an ash and an alder tree on Earth. Ages later, his son Thor journeys to King Mirmir with a branch from Yggdrasill, the World Tree, and gives it to him. Mirmir stirs his enchanted fountain with the branch and liquid drops fall onto the ash and alder tree on Midgard (Earth). They transform into Aske and Embla, the first humans.

The Kree encounter these Eternals and are inspired to begin researching their own genetic experiments on humans, much later resulting in the Inhumans (What If 26-28).
- The Eternal, Chronos, raises two offspring, the war-like Zuras and the peaceful A'Lars (later Mentor).
