Or perhaps  they formed directly after the big bang from the primordial gas collapsing in on itself?

或者，它们可能是在大爆炸后直接形成的，原始气体自行坍缩？

It's probably older than any rock you can find anywhere on Earth because it formed from the primordial gas cloud, that nebula that collapsed to form the sun and the planets over four and a half billion years ago.

也许比地球上所有的岩石还要久远，这是因为它诞生于最原始的星云团，这个星云团在 45 亿年前形成了太阳和各大行星。
