As the family sat together, discussing their recent victory over the Sirians in the game of "Eldrida, but with Aliens," they began to understand the true motif behind the Sirians' actions.
"So they weren't trying to defeat us," Lucien said, "They were trying to get us to join the Galactic Federation of Post-Sapient Species."
"That's right," Jonn'Sena, the Martian, confirmed. "The Sirians believe that humanity has the potential to become a valuable member of the federation and they wanted to test our ability to work together and think strategically."
"But why didn't they just tell us that from the beginning?" Calian asked.
"They wanted to see if humanity was ready for such a responsibility," Lirien, now in her Martian body, explained. "They needed to see if we were capable of understanding the complexity of intergalactic politics and diplomacy."
The family was in awe of the revelation. They had never thought of themselves as capable of such a grand task. But they also knew that they couldn't let this opportunity slip away.
"We need to contact NASA and tell them what we've learned," Lucien said. "We need to let them know that we're ready to join the federation and that we're ready to take on the responsibility that comes with it."
And so, the family contacted NASA and shared their newfound knowledge. The government agency was skeptical at first, but as the family provided more information and evidence, they began to see the potential benefits of joining the federation.
With the help of Jonn'Sena and Sir Puffy Mittens, who had become a valuable asset in the game of "Eldrida, but with Aliens," the family was able to convince NASA to take the necessary steps to join the federation.
And so, humanity took its first steps towards becoming a post-sapient species and joining the Galactic Federation of Post-Sapient Species. The family had played a crucial role in this achievement and they knew that this was just the beginning of a new and exciting journey for humanity.
