So Superman is still traveling forward in time until he gets to 801,970 and decides to drop in on Earth. He finds that the earth is entirely barren and a completely dead planet. Then he gets a great idea. Let's look at his to-do list
1) Drill through the Earth
2) Split it open and then weld the two halves together
3) Ignore the fact that there is no way in hell that this planet will have any gravity!
4) Suck some wind (that sounded kinda wrong)
5) Spread his seed (Whoa!! It just keeps getting worse, folks!)
6) Cultivating some weed and planting some bush.
7) Fly weird animals through space
8) Locate humanoids, ignoring smurf-caveman on right.
9) Kidnap hot cave-couple
10) Stand back and gloat as cave-couple discovers that everything on the planet is poisonous to them
