In the first place it gives people the idea that they don't have to care for this world because it is nit their home anyway. The truth is, this is their physical home, and will be the physical home of those who come after. We need to not only love and accept ourselves as we are, but also each other, and our planet. We need to breath, move and live in harmony with our physical home, for the sake of any future generations of man. Secondly you don't need saving. There is nothing wrong with you, you are perfect, you just don't remember this Truth. It is in our ignorance of the Truth of who we are that we harm each other and our planet.
Let's say that this information has been passed down, from president to president, and not only that, the same information is known by the other major leaders of each nation. So Russia, China, North Korea, Japan, Israel – everything. They all know it. They have all keep it secret from their citizens. Why is obvious. If we knew were were going to die anyway, in the very near future, all hell would break out on the planet.
But as this globally catastrophic event nearer, the truce is crumbling, because these leaders all know the end is coming soon. Maybe we haven't been able to get things working yet so we can save people, or maybe we have, the select few who will be saved have been chosen and will be whisked away, while the rest of us will face the end of the world together.
