another anecdote is,

"A star which we see today must have emitted that light billions of years ago, at the same time when Dinosaurs roamed the earth. To a planet roaming around that star, our sun would be another star. Any one seeing our sun from that distance would see the light emitted by our sun billions of year ago.

So, much so that, if they were using similar telescopes like us, they would actually see dinosaurs, and not us."

Its actually overwhelming and mindblowing to even think that way.

You are wondering about this picture. Just imagine, "light" needs 4.3 years to go from earth to the star nearest to our solar system. And there is nothing but "empty" space in between. Think about it for size.
