getting started

reducing world ere photosynthesis
spewed oxygen free in our atmosphere
replete with fuel when none knew what that is
and lightning bolts could kindle no flame there
pyrimidines form fast by gas-discharge
but ribose hasn't been found in that mix
and RNA's a barrier to large
to surmount without learning some more tricks
aminooxazole may prove the key
to prebiotic macromolecules
to build replicating machinery
without invoking biologic tools
one common ancestor stamped all our genes
by knowing that, we're baffled by the means
