your missing the point.
It is this mere striving for the understanding of existence that makes up our life, what gives us fufilment. If i may borrow another quote "many men spend their entire lives fishing, without ever knowing what the fish is." So, my point is that existance is different to every person, and every living thig. We are not searching for the same thing, every person strives for a different goal and a different path to fufilment. Arguing about the nature of life is stupid, because it is our own perception of the world that dictates our "existence" and "meaning." So, waht does it matter of the earth is flat, round, or simply a bridge between portions of space time, it is your mind, and your mind alone that will prove to you the truth. And opnce you believe that, true "reality" dosnt really matter.
