Not because we think that it's still about to happen,
thus makes our future life as though yet to be exist.
Human mind can't yet perceive the nature of future.

When truth is so bitter, people tend to bury and avoid it.

There are people who desperately want to change the world.
I wonder if it could be measured, because the world is already
in the state of continuously change since the beginning of time.
Or they may just want their names etched nicely on men history.

Time is an illusion that arises from the educated perception of human senses and mind to the changes that happened. Stop the changes, or terminate the educated perception, then time will cease to exist.

Each man lives in many worlds within different life.
Mind can only see world in which it lived and located.

The real funny thing is, whether the demons exist or not at all in your life, it's nothing to do whether you believe or not to one, none nor both of them.
