Let it be known!
When I die I wish for my body to be hurled into space so that it goes into a continuous orbit around either the earth or the sun, and I know that is currently impossible but I don't plan on dying for a while yet. After I have entered this orbit, debris (funny word) should begin to build up on me, so that over billions of years I become something of a giant planet. Over a few more billions of years I will then form an atmosphere and, with any luck, life will form. Skip ahead even more billions of years and intelligent life will evolve, and a war will be fought on my face. In a sense I will be a god of this planet, which will undoubtedly out shine my friend's monument he plans to have built in his honour on this doomed planet.
