古老陨石坑把深时变成争论
A crater is never just a hole in the ground. If it is real, and if its age is correct, it becomes a timestamp from a violent chapter in Earth's history. That is why claims about extremely ancient impact structures attract both excitement and resistance.
The proposed structure in Western Australia matters because its possible age reaches back toward a planet very different from the one we know. Continents were still being shaped, the atmosphere was changing, and life had not yet made Earth look familiar.
