Awakening.
From the insights, Alex came to know that there will come an event where all the people of Earth would be involved in this Gods, Blesseds, otherworldly deities, and so on stuff.
There's no escaping this and everyone will be given an opportunity to survive through the means of awakening.
Just like how Alex had a system and the Blesseds had one too, everyone will awaken this system thing and as per their body constitution, develop the required attributes and earn a certain class.
Alex didn't know about himself since his path was much different than the rest, but the Blesseds that have a system, they have been fully awakened.
Once a person gets their attributes and class, they would be considered ready to start their survival journey.
It was basically similar to being thrown into a RPG and made to level up like crazy to survive and fight enemies.
