The civilisation as we see today on our home planet Earth is a way that may lead to our devastation, humans getting perished not only due to its errors but may be due to natural disasters or alien attacks for which humans should keep them ready for any such eventuality rather than fighting between themselves for trivial things and remain united.
The alien force comes down heavily on earth, humans lose the war without any fight. Now it's the time to retrospect the life humans were living before the alien invasion and what should be the duty of humans towards mother EARTH as the most advanced CIVILIZATION of this unique planet.
