作曲 : 这是V启
作词 : Stephen William Hawking
The questions i would like to talk about are：
one
where did we come from？
how did the universe come from into being？
what is the future of the human race？
is there alien life out there？
are we alone in the universe？
i now turn to the second big question：
are we alone，or is there other life in the universe？
we believe that life arose spontaneously on the Earth，
so it must be possible for life to appear on other suitable planets，
of which there seem to be a large number in the galaxy.
but we don't know how life first appeared.
this brings me to the last of the big questions：
the future of the human race.
if we are the only intelligent beings in the galaxy，
we should make sure we survive and continue.
i think it quite likely that we are the only civilization
within several hundred light years；
otherwise we would have heard radio waves.
the alternative is that civilizations don’t last very long，
but destroy themselves.
