Is Anything Eternal?

Life is short on the grand scale,
just a tick on the spectrum of eternity.
People's faces come and fade
on waves of an ebbing tide.
Even things that we see as everlasting:
water evaporates, earth erodes,
emotions change in the blink of an eye.
Though we have words such as
Permanent,
Eternal,
Forever,
can anything really stand the test of time?
