The human race has only two options
為了尋找高等外星生物
when it comes to looking for advanced aliens.
人類只有兩種選擇
We can listen, or we can be more active
靜靜傾聽，抑或更主動一些
and broadcast our willingness to talk.
向宇宙發布我們與外星人交流的期待
We'd have to think very carefully about what we might say.
我們必須謹慎考慮將要說的話
I think this might be just a little too risky.
我認為這有些過于冒險
We only have to look at ourselves to see
我們看看自己就能明白
how intelligent life might develop into something we wouldn't want to meet.
智能生物已達到的發達程度，也許還是不見為妙
We humans are already capable of manipulating the course of our own evolution.
我們人類已經掌握了控制自身進化的技術
Exactly the same, presumably, would be true of advanced extraterrestrials.
假設，高級外星人也具備相同能力
Ultimately, they could halt aging and become virtually immortal.
他們也許最終能夠停止衰老，甚至長生不老
What's more,
不僅如此
they might have reached that point millions of years ago.
他們可能早在百萬年前就已達到這種水平
It might sound unlikely,
這聽起來也許有些聳人聽聞
but if you think about it logically,
但如果按邏輯推理一下
alien technology should be
就能想到，外星人的技術
as extraordinary to us as a rocket ship to a caveman.
絕不會遜色于我們從山頂洞人發展到制造火箭
I imagine they might exist in massive ships like these,
我覺得他們耗盡了自己星球的所有能源后
having used up all the resources from the home planet below.
可能生活于這樣的大型飛船中
Such advanced aliens would perhaps become nomads
此類高等外星生物也許會成為游牧物種
looking to conquer and colonize whatever planets they can reach.
伺機征服并掌控任何能夠達到的星球
If so, it makes sense for them to exploit each new planet for
當真如此，也難怪他們會尋找新的星球
materials to build more spaceships so they could move on.
搜集更多搭建飛船的材料以維持航行
Who knows what the limits would be?
誰知道有什么阻擋得了他們
