Our journey starts in the far south west,
我们的旅程始自遥远的非洲西南部
in the oldest and strangest corner of the continent.
是非洲大陆上最古老最人迹罕至的角落
Here, the thirsty land is covered
在这里 干涸的大地
with thousands upon thousands of circles.
被成千上万个神秘怪圈所覆盖
We still don't know their origins.
我们至今未知它们的成因
Poisonous plants, foraging insects
有毒植物 觅食昆虫
and even magnetism have all been suggested,
甚至磁场都曾被列为假设原因
but each ruled out.
但最终均被排除
The circles don't move, and their shape never varies.
那些圆圈不会移动 亦不会变化
They're unchanging, much like this part of Africa itself.
如同非洲这一片地区一样 亘古不变
Ancient and arid, it almost never rains on this land,
古老而又干旱 这片土地几乎从不降雨
yet there is water here, hidden away.
但却有水源存在 只是深深隐藏了
To survive here, life must use every trick in the book.
想要在这里生存 所有生灵都必须使出各门绝活
