Effectively (and without trying to make this sound like The Matrix), what if you, YES YOU, are the only actual living person on Earth, and everything you experience is merely sensory transmissions within a highly controlled environment manipulated by an alien race (possibly even humanoid) in an effort to determine whether continuance of the human race on earth is a feasible business--the business goal is undefined. You are totally unaware of being the subject of this study. Keep in mind the following:
1. Those things you value may not be valued by the host alien scientists-- id est- you elect to drive your car so the alien scientists deduct that consumption of natural resources is something you value, vs, say, you elect to erect solar panels, so the alien scientists conclude that using renewable energy is something you value. What you might think is good they might see as weird or pointless-- "Why wouldn't this human subject use vast natural resources (oil) when they are available" or, "Why does this human subject elect to use solar power which costs more to develop and maintain over time?" So everything you do will be looked at from multiple angles and you yourself do not understand or can not even imagine the ramifications of your decisions and actions.
2. How you spend your time is observed as an empirical result of what you value. If you work then the alien scientists are going to think that there is a high personal value on attaining money; or they might think that the human species needs to have some sort of busy-work in order to survive. If you spend a few hours a dy on the internet or watching television, the alien scientists might think that the human speicies requires alone time away from other people or that humans must be entertained (for example).
3. At the end of your life the Earth (humans, and all fauna and flora) are either destroyed due to your failures or flourishing due to your successes. However, you can not define what is failure and what is success.
So the question is: How do you conduct yourself? How do you conduct your life?
