The reason the night sky never changes over millennia is that the stars we can see through our atmosphere are also moving through the Galaxy with us. Barnard's star moves quite a bit per year at 6 light years. We can also calculate stellar parallax based on knowing our orbit diameter around the sun and making a few observations. This is how we know how far away some stars are.
Northern Hemisphere population is 6.96 billion people (87.0% of the earth's total human population). Southern Hemisphere population is 1.04 billion people (13% of the population).
There are lots of amateur videos of shooting stars going every direction, including towards the camera and upward from the horizon.
