Life is a descendent from paradise. From the perfection of paradise to the imperfection of Earth.
Druids believes human purpose on Earth was to know everything on Earth and simulate them into harmony: the Ecosystem of Harmony.
The Purpose of Life in druidic faith is basically to collect the knowledge of everything on Earth and how they works so that every creature can be given a place in an ecosystem where their needs will be fulfilled and their activities integrated in a harmony. From the imperfection of Life on Earth, Druids strive to Return to Perfection.
21st century's Project Atlas was pre-Druid conception: to shoulder all the troubles of the Earth, and to solve them all.
After Life
Druid believes that humanity is in pending judgment from how they administrate the Earth, how far they are from reaching harmony in the Ecosystem of Harmony.
Every human was judged from how they make their life, what kind of worldview they are living in and what kind result they expected to get from their activities and the gap with the actual result. There's also the calculation of sins and rewards from their activities, but druids put a lot of attention on the worldview each human makes, what kind of world they are living in.
Since humanity is in pending judgment, when a human died, they are not yet to be judged of his life, but waiting for the Day of Judgment.
Someday the world will end and every living creatures will die, and the world will be rebuilt anew and everybody will be resurrected to be judged of his life. That was the Day of Judgment.
There will be the record of everything and every human will be judged by all of his actions and its consequences.
Concept to Note:
Druidic Concept - Absolute Truth: All knowledge where every truth is present and every lies is confronted and noted where it come from. The truth where there can be no doubt.
