Lets take a walk with a simple concept.
Light can only exist because of darkness, or you could say, light implies darkness.
In our 3D world without the shade of black, there could not be the shade white, again black implies white.
Without death, there could be no life, for life to exist there must be death.
If you accept everything up to this point, its not too far a stretch to see that your existence in this world, this universe at this time is absolutely fundamental.
Without YOUR life, the universe that you are a part of can no longer exist. You are fundamental to the existence of this universe, and the only logical question to ask next is.
What are you going to do about it?
