Altair in Aquila, the eagle, and Arcturus in Boötes, the herdsman, are two bright, naked-eye stars that have relatively high proper-motion values (0.66 and 2.28 arc seconds per year, respectively). This you can check with minimum equipment or expertise.Ever really think about this?
Two dimmer stars, named Tarazed and Alshain, flank Altair. In the modern sky, these stars form a bent line, with Altair in the middle — as if those flanking stars are the eagle's "ears." A thousand years ago, Altair sat directly between them, and in Babylonian times, Altair was "below" them, making the two flanking stars seem more like "antennae."
In fact apps like Star walk 2 let you check the position of celestial bodies throughout history; so no, sorry, mainstream science does not say that the sky configuration does not change over time. That video is just BS
