A team of geologists from Curtin University has discovered unequivocal evidence for a hypervelocity meteorite impact 3.47 billion years ago (Archean Eon) in the center of the Pilbara region in Western Australia.
The impact of Theia would in my unscientific opinion be a far better suspect. It both tore away lots of lighter material that would have made the crust too thick for continental drift, while adding to and remixing the remainder.
Nice sciencing.
TIL continents might be (basically/poetically) just ancient impact sites.
