Built Solar System §10–12; Additions §1.

Origin (lifeOrigin) | What it does |
|---|---|
| abiogenesis | the default |
| panspermia | arrives from elsewhere: odds ×12, tides and vents do not matter |
| divine | placed at a chosen time, whatever the conditions |
| introduced | placed at a chosen stage (microbes, complex cells or animals); the first Aeon is the Xenozoic |
Chemistry (biochemistry) | Solvent liquid at |
|---|---|
| carbon-water (default) | 273–373 K |
| carbon-ammonia | 195–330 K |
| carbon-hydrocarbon | 90–185 K |
| silicon-sulfuric | 283–610 K |
