Project Revive

After the extinction of humanity, caused by unknown events, extraterrestrials that were travelling the galaxy seemed to take an interest in the bright blue planet. Upon further inspection it seemed that the planet wasn't completely barren of life, but it wasn't in a good condition either. While the extraterrestrials were beckoned back to their ship to further explore the galaxy, a few stayed behind. They had seen some sort of potential in the world around them, and with the scale of the planet itself, they tasked themselves to help rebuild the planet back to it's former wild glory.
