Goes on every time a new star gets crushed by gravity out of the gas clouds. It took a long time for astronomers to figure out where the water was coming from, but there it is, water ~ burned hydrogen ~ spewing out at the poles ~ in vasts quantities. I mention that just in case somebody wanted to know where water comes from ~ there it is, from the very fountains of heaven ~ it boils up with the ingredients of life, and probably in every conceivable mix ~ creating the genes and other structures long before the critters!
We could probably do it.

Let's all give a big huzzah for broken symmetry.
