Humanity was no longer confined to the Earth. Which was a good thing, because the Earth was no longer habitable. We destroyed it. But necessity is the mother of invention. So, after abusing one mother, we turned to another to save us.
We learned to terraform
planets, making them more like the home we'd so callously destroyed. We
mastered gravity and learned how to protect the human body
during high-gravity maneuvers. Both of these things were essential to space
travel.
Try as we might, we could not develop ships capable of traveling faster than
light.
We did, however, theorize how to create stable wormholes through space. To create a wormhole we needed a gate at both our point of departure and our destination. So we did what we always do. We sent
great colony ships, unimaginatively known as "arks," out into the universe.
Two of these managed to find suitable worlds for humans to inhabit.
When we finally received their first messages, we learned two very important
things that would change the course of human history....
1) We were alone in the universe
2) They had completed constructing the wormhole gates
The humans remaining in the Sol system quickly went to work building their
own gate, and within a few generations, and the interstellar gate network was
created. By the time all three systems had been linked, terraforming was
already underway. Humanity had reached for the stars, and now we would
bend them to our will.
