I definitely think the fallen and nephelim live in Antarctica. The reason I think we can't visit is because there's a wall there that separates them from us. They travel underground to come on our side. I know some people don't believe in "flat earth". But the more research I do the more I believe it is true. What they call "outer space" is actually outside the wall.
Back to where I said that they tell us in plain sight.... Attack on Titan tells this story very well. Humans live inside these 3 walls, outside of them the "Titans" (or giant/nephelim) live. Also in the anime it's stated that the titans don't actually hunger or thirst, but they eat people anyway.
Enoch 7:1-4
1.And they took wives for themselves and everyone chose for himself one each. And they began to go into them and were promiscuous with them. And they taught them charms and spells, and they showed them the cutting of roots and trees.
2 And they became pregnant and bore large giants. And their height was three thousand cubits.
3 These devoured all the toil of men; until men were unable to sustain them.
4 And the giants turned against them in order to devour men.
Enoch 15:11-12
11 And the spirits of the giants do wrong, are corrupt, attack, fight, break on the Earth, and cause sorrow. And they eat no food, do not thirst, and are not observed.
12 And these spirits will rise against the sons of men, and against the women, because they came out of them during the days of slaughter and destruction.
