One of the problems they may face, is too much information. On the other hand, they may not be able to read what we have written. English has changed a lot over the past 800 years, and is likely to change a lot over the next 800 years.

Assuming they can understand what's being written, then they will have a strange view of us. They will see us as very divided. They will thin we can't agree if the moon landing happened, or if Covid was a hoax.
