Comment Were there even enough Heavy Elements at 15MY? (Score 0) 312
I'm sure there was plenty of Hydrogen, and probably a lot of Helium at that point, but given that life (as we know it) depends on, at very least, elements up to Sodium (Atomic Number 11), and heaver elements are the result of nucleosynthesis in the exploding cores of dying stars, even with water around, were there enough heavier elements to support life? Was there even enough Oxygen around to form water, regardless of the temperature?
