Upon the creation of the first living cells (or even if those cells landed here from elsewhere in the cosmos) those cells had to ingest or absorb some kind of life supporting sustenance. If the cells didn't start eating each other right from the start (predator and prey system), and if these cells couldn't absorb nutrients from the ground (a root system) then all that was left for sustenance was water and the sun.
- Could a living cell thrive on just oxygen and hydrogen, along with nutrients from the sun?
- Are there any life forms today that are surviving on just these three sources?
