Signs of life

Excerpt from the NASA ROCKS collection

John Thomas Clark 26 October 2008

Three point five billion years ago this globe
supported life – so says some science probe
of South Africa. The light of this strobe,
shining on exposed rock, shows a microbe

lived in the sea and ate hardened lava
having no plants, animals to eat. Brava!
That’s rock, water, life – Break out the kava –
no more Martian or moon probes; we have a

winner! So, maybe now, we can explore
some other worlds right here on the earth floor –
real, live kids whose daily survival chore
is to confront the mite-like omnivore

that stews and devours each rock-hard muscle,
corpuscle by red, white and blue corpuscle.
