David,

In your comment about Tom Gold, you state that "there is some recent
support for the origin of life at high temperature such as a hydrothermal
vent setting."

I'm aware of biological activity associated with, and supported by
hydrothermal vents on ocean bottoms, often using sulfide as nutrient, but is
it correct to say that life "originates" there? Similarly, to state that
"recent experiments have been able to create biologically important
molecules under hot vent-like conditions" does not, to me, suggest that life
is created. Am I missing something here (I'm about as far from life
sciences as possible)

Not trying to be picky, just wondering.
