You could pull up the scenario that any race you find....might be 100 million years more advanced, so it’d be like Einstein trying to converse with a 4-year old kid.

You’ve been watching too much Star Wars.
Heck, if another civilization is only 50 years advanced from us it would be like Einstein trying to converse with a four-year old
Just compare our knowledge base from 50 years ago with that of today. A LINEAR extrapolation of human knowledge (and it’s never ‘linear’) boggles the mind.
