Outer space is real. It's where all the stars are, including our sun and moon, which are millions of miles away, and not within the atmosphere of the earth, and the stars aren't either. Denial won't change that fact. Stars make up our galaxy, various globular clusters, and even the Pleiades and Orion. Stars also make up other galaxies, like the Whirlpool Galaxy, Andromeda, and countless others. The idea of stars literally falling from outer space to the earth is an impossibility, given how massive they really are. That verse about the stars falling from the sky is symbolic language.
The largest known star in our galaxy is UY Scuti, which is found in the constellation Scutum, is 7 to 10 times the mass of our sun. To give you an idea of how massive it is, the diameter would reach from the sun to the orbit of Saturn.
UY Scuti - Wikipedia
It was known to exist back in 1860, but they had no idea how massive it was, but we do now.
One more time: the earth is not flat.
Simple astronomy completely demolishes it and any interpretation of scripture that seems to support the fallacy and fantasy of a flat earth. A spherical earth is 100% fact. There are two different sets of circumpolar constellations. There's one in the northern hemisphere, and one in the southern hemisphere. Polaris is only the pole star for northern latitudes. There are three constellations that mainly serve as the circumpolar constellations in the southern hemisphere: Carina, Centaurus, and the Southern Cross. The latter is probably very familiar - it looks like this:

The closest thing the southern hemisphere has to a pole star like Polaris is Sigma Octantis.
