dialogue
Possible
answer:
We
have
just
received
a
message
from
our
spaceship
to
Mars.
Our
spaceship
has
discovered
aliens
there.
They
have
never
sent
us
a
message
because
they
don’t
know
how
to
communicate
with
us.
They
have
not
visited
the
earth
because
they
don’t
know
how
to
fly
to
our
planet,
and
they
prefer
life
on
Mars.
They
seem
very
happy
on
their
planet.
They
have
used
parts
from
the
other
spaceships
from
the
earth
to
make
TVs,
radios,
etc.
We
hope
they
don’t
do
the
same
with
this
one!
