From Cavemen to Post-Human

From the first cavemen clinging to some logs,
escaping with their lives from flood or slaughter,
to mega-palaces that cruise the water,
humans became amphibious as frogs.
Then into space: hostile environment,
no barrier to ways to stay alive,
no worse in Mars domes, modules at L5
than in an igloo or a desert tent.
Next, thought balloons by tech cut free of place,
drifting connecting through ethereal skies,
where we upload ourselves as thought and rise
into the cloud as a post-human race
in new non-human landscapes without land,
pure energy as a new tribal band.
