Melkweg doesn't like humans,so he goes to other planets to have fun wrestling his brother. As he goes there he gets a plan to make all the humans not 'pollute' the universe. Now the entire universe is his playground.
Zeus and his family have been on the throne for about 1000 years.It has been 1000 years of none stop arguing. As Prometheus the Titan created the humans,many gods and titans were against this. They thought that humans would become too smart and stop worshiping them, and some gods even thought that humans were like pollution,always getting in the way of stuff. One of these gods was Melkweg.
One of these gods was Melkweg. He was VERY angry at Prometheus because the humans always stopped Melkweg and his brother from wrestling. Earth was Melkweg’s playground,but Zeus said that with the humans there he could wrestle with his brother.
This made Melkweg very mad. For the next few hundred years Melkweg was trying to find a new playground world. He went to mars and him and his brother wrestled there for a few hundred years,but as they wrestled they hit the ground so hard that the crust broke! They named this crack the Valles Marineris. It turns out that this is the largest canyon in the solar system.
They then went to Venus and wrestled there for a hundred years,but his brother got sick and made the atmosphere turn into sulfuric acid. Once he got better,they went back to earth to check on the gods,and they found out that the humans found fire! Melkweg told his brother “these humans are advancing too fast, soon they might pollute the rest of the universe with life and keep us from wrestling. I will think of a plan.
Then for a 10 thousand years they thought of a plan. At last,he finished making his plan. He would make the universe always expand away from the puny humans and make it where they couldn't reach anymore planets. The only problem with his plan is that him and his brother weren't powerful to make the entire universe expand. So he had to try to trick Zeus in making the universe expand.
He went to Zeus and said “if we made the universe expand then we could challenge the humans. If they do reach other worlds then that means they will be truly advanced,and if they don't, that means that life is not worthy of expanding.” Zeus took the bet,and began the expansion of the universe. To this day Zeus still thinks that it is benefitting the humans,but it was just a plot to make it were life won't pollute Melkwegs playground.
