The ceased to exist when the star stops to expand and melts -- when it can will itself to shine again and starts looking for ways to become a shining star again -- when it becomes a star, it becomes a nuclear reactor. A nuclear reactor is defined a device in which a nuclear fission chain reaction occurs under controlled conditions so that the heat yield can be harnessed or the neutron beams utilized and all commercial reactors are thermal reactors, using a moderator to slow down the neutrons (Glossary of Uranium Industry Terms, n.d.). The human existence will have no say at the time of our death for we are just particles -- a tiny piece of an atom that can all be destroyed with a nuclear reactor.

The humans evolved through the dreams made by the singularity, each vision it sees creates what we have now. If it stops visualizing the vision, the creation expires.

The humans' fate is not ruled by their freewill -- their existence and choices in life is merely part of the singularity's creations. The singularity or we can all it as the "Powers that be," creates the situation in a predetermined manner -- humans think that they make decisions by reflecting on their actions, on contemplating on how to make a choice; but in reality, everything is like a 'Choose Your Own Adventure' book. In these kinds of book, the reader is usually asked to decide on the leading character's next course of action -- it seems that the reader has the 'power' to choose but really, everything about...

In life, humans tend to think that they chose their own adventures but all of their actions already have a corresponding response and result that the singularity already thought of.
To have a choice, it seems, is to have genuine options or alternatives -- different ways in which one can act -- determinism requires that what humans do is the only thing they can do, and that because of this humans never really have a choice about anything, as opposed to being under, perhaps unavoidable illusion, that humans have a choice; for those who argue for incompatibilism in this means might give up that the reality of determinism is constant with our making choices, at least in the sense in which a chess-playing computer make choices, and consistent also with our choices being causally effective but this is not enough for free will (Honderich, 1988).
