Welcome home not yet born brothers
who left the earth in future times
traveling near the speed of light
headed toward alien climes.

The voyage for you took only years
while thousands passed those left behind
thanks to that devil, time dilation
as discerned in Albert's mind.

Perhaps a navigation error
whenever traveling so fast
has landed a few of your fellows
a goodly distance into their past.

And having evolved over time
you look a little strange to us
smaller, slimmer, larger heads
I guess these changes were a plus.

So we see you flitting in our sky
in evolved bodies, ships and all
fleeing back into relative space
to you are we Neanderthal?

Can't really say that I blame you,
we're kinda primitive I know
we've just now started thinking that
you're Us and not some UFO.
