In the sky

Through a telescope from Earth
Light's journey
The light you see tonight set out 10 thousand years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 185 million years.
The Sun seen from there
From a planet around OGLE-2018-BLG-0740L, the Sun would look like a star of magnitude 17.36, in the direction where our sky has the constellation Auriga. It would be invisible to the naked eye.
