The first

We were the first then
the galaxy we explored
no other life was found
so we were alone then
.
on the planets we visited
so the life we seeded
then a ritual we instituted
when we were close to dying
.
on a planet well chosen
so our life we’re going to end
a catalyst we are swallowing
our body will be dissolved
.
so the planet will be seeded
thus our death will have created
a planet that will be inhabited
in millions of years or around
