Simply landing on a piece of land edge with ice and snow does not give you any real knowledge of where you actually are.
Well, that combined with...
When I was there in the early part of the year it was daylight at midnight.
... does (or at least can, if you'll let it) tell you a lot.
I think you said you arrived in February. Was the Sun up 24 hours a day in the earliest parts of your visit, or was it twilight for part of the time then? If it was 24-hr sunlight, do you know approximately the date the Sun first touched or went below the horizon?
You were on a coastline, I think (is that what "land edge" means here?) Were there mountains, or was the dry or ice-covered land generally flat, or somewhere between? By "mountains", I mean Alpine Peaks - high, jagged ones.
Did you arrive by ship, air, or overland? I asked this a couple days ago and got little more in response than a lecture about how I should not ridicule you.
It certainly doesn't give you me any thoughts of being on a globe that's for sure, in fact I'd say quite the opposite.
FTFY.
Really? None at all?
The sun traveling a tilted circle in the sky, lowest directly south until it ducks below the horizon doesn't suggest exactly that? OK. For you maybe. For me it absolutely does, which is why I resent the second-person pronoun in your quote.
How about you getting a brain because it's clear you haven't been there.
This quote wasn't addressed to me and doesn't apply since I
was in Antarctica in the early part of the year, but how this relates to anyone "having a brain" is not clear. What was that you were requesting about ridicule?
