How realistic/unrealistic is the trope of "The Earth that Was"?

The idea of the trope is that at some point, Earth is doomed, humans flee into the stars, knowledge of Earth is lost in the process, eventually becoming legend or myth, either due to loss of information, revisionism due to state propaganda, or even something gone horribly wrong in the early days.

So, the question is: in reality, is this trope a viable scenario (even if temporary) or is it unrealistic from the start?
