Heaven vs. the singularity

Differences between the singularity and heaven include:

1. The hypothetical future existence of the singularity is based on logical arguments about real-world observations; the hypothesized existence of heaven is based entirely upon works of theist mythology.
2. The singularity will not happen if civilization collapses; heaven has supposedly existed since the creation of the Earth.
3. Whether or not we as individuals end up making it into the singularity depends less on our individual actions and more on the progress of technology and history (see #1); our entry into heaven, on the other hand, is supposedly governed by the decisions of one particular entity ("God") regarding the morality of our behavior as individuals.
