They mentioned you can go to a settlement on Mars, so you can visit the Sol system, but Earth hasn’t been mentioned. Either it’s off-limits, like in Elite Dangerous where you need a permit to visit, or it’s heavily altered, perhaps by nuclear war or climate change so they don’t have to recreate all of Earth, or they actually have recreated all of Earth.
There was the day one patch notes that was being mentioned a few days ago. One of the fixes mentions an Earth Landmark. So presumably a unique location you can visit on Earth, one that isn’t completely randomly generated.
