First they don't do construction in Antarctica so that was straight up fabrication.
Yes, they do a lot of site construction in Antarctica. This is the Amundsen-Scott Research
Station, just metres from the actual South Pole:

And this is an American construction crew working on a wharf installation:

Also there may not be an ice all per se - just like a continent that is circular, enclosing our known world - cross over the continent and you come to the infinite ocean plane, and there may be other worlds out there like our own, tiling this ocean plane at odd intervals, to all infinity.
I notice that you use the word "may" a couple of times. Do you have any empirical evidence
supporting these claims of infinite oceans and other worlds, or are you simply guessing?
We have not been "back" to the moon b/c that was an expensive scam to film, lol.
Yes we have been back to the moon; six times in fact. 12 men have walked on the lunar surface,
and six drove Lunar Roving Vehicles as part of the last three missions. Three men have been to
the Moon twice. Apollo 17 was the final manned landing in December 1972.
And only CIA / military etc. can get to Antarctica b/c they are in on the coverup.
Nope. This notion is nothing more than a conspiracy theory maintained by some flat earthers.
Any private citizen can travel there by sea or air, land there and explore it themselves in guided
tours.
