I think they're lying to us. I don't know what Earth really looks like. However, it's not this marble hurtling through some fictional space.
The reasons for this lie are to sell us the theory of evolution, to make us feel insignificant and small, and to deny the Creator.
"You are a being that arose by chance in a vast universe, completely insignificant and small, and your life is equally insignificant in the face of billions of years of evolution."

Meanwhile, to this day, no ordinary person has flown into space, only a bunch of Freemasons and super-rich/celebrities.
Incidentally, no one has actually circumnavigated the Earth from north to south.
They won't let you explore Antarctica and have declared it a restricted zone, and strangely enough, even hostile nations can easily agree on this.
They are united in this matter. Of course, only to protect penguins, etc.

Apart from that, you can see much farther than it should be possible on a sphere with a circumference of approximately 40,000 km.
Then there's the matter of flight routes, etc.
The fact that NASA is an esoteric/religious/occult organization, if you look a little closer...
The strange trajectory of rockets
And much more
