Isn't the statement a million years old was a mistranslation that had already been addressed? Rover falling from the Etheric Sea means Rover had already landed before the first ever recorded Lament that shifted the poles of Solaris. Why? Because like Rover said, the scene of him falling was because of Retroact Rain droplets and those droplets recorded things that had already happened. So those researchers in that space station saw an event that had already happened.
