CONTEXT: The planet was toxic due to the waste that humanity created. As such, any soil and water would kill the plants that grew there, and it was no longer feasible for humanity to stay. The plant is proof that Earth is ready to produce life again. The soil and the water are safe enough for a plant to grow with them. It's not infeasible to think that the ship had a seed vault in it, given its phenomenal size, and original mission was to return to Earth at some point.  <sep>  Q: How can the Axiom computer know Earth is safe based on the one little plant EVE found?
