13,800 million years ago the universe went boom
13,200 million years ago the Milky Way happened
4,540 million years ago Earth came to be
3,550 million years ago life started as cyanobacteria
65 million years ago emerged the first primates
So many years ago, the Big Bang boomed,
thirteen-point-eight, well, billion, more or less.
Two-thirds the time since then passed, then Earth bloomed–
at least, into one rock it coalesced.
Another billion years, then life was formed:
bacteria that fossils show’s like ours.
Mutations’ prevalence helped those deformed
evolve past ever higher complex bars.
The primate came just sixty-five mil years
ago. Let’s look at ratios. Divide
that into age of universe: it nears
two-hundred times! 3 billion years supplied
enough to make such beasts as us. There must
be others hid in interstellar dust.
