No other atom is as abundant in our still-maturing cosmos as the lightest and simplest of all, hydrogen. Those two atoms, H and He, are the primary material bequest of the old universe of hot and uniform gas before the stars formed. No other atomic species now numbers as many as one in 1,000 of the hydrogen population. All the others, common or rare, are products of some complex alchemy in the stars, whence some atoms are driven explosively into space, as others drift slowly out. The third most common atom of all is the oxygen we breathe, the sun's legacy from stars gone by, whose debris of dust and gas was gathered up once into the forming sun.
Molecules are all but absent.
That prodigious organism had a mind structured by repeated but fleeting pulses and waves moving within starry plasma. Our favored model for life is much less imaginative. We see life as carbonaceous molecular structures, in HOH solvent, open to change. The rocky earth, dense and partly solid, is atomically mostly oxygen, two atoms out of every three. Some rocky moons of the planets are similar.
