Photos look like they could have been taken on Mars.

As for humans living there even 10 - 12,000 years ago, I highly doubt it. No land to even spring agriculture, it's a desert.
As for people visiting there before our historical records, who knows, maybe. If they did, it wasn't for a long time.
But, to address your post directly, there is tons of life teeming around beneath the glaciers and ice, Antarctica has dozens of 'active' or dormant volcanoes.
Ice at the bottom of the borehole was deposited about 70,000 years ago; ice about one-sixth of the way up about 50,000 years ago; and ice about one-third of the way to the surface 20,000 years ago.

That article says that the Antarctic ice warms faster than the rest of the planet. It doesn't say that Antarctica was ice free 20,000 year ago. By a long shot.

The image I highlighted is essentially ice-free now. I don't know if it was ever covered with ice. Might be something to look into, particularly there and the surrounding areas and the lower sides of the mountains. Get a nice warm current coming from somewhere, a bit of post-Ice Age warming, and maybe it would be possible to grow something useful. There are a couple of nice, warm currents dropping down from Brazil and Eastern Africa into the Prince Astrid Coast. During a period of post-Ice Age warming when the currents might have been disrupted, it might have been significant.

Antarctica is cold because of the weather patterns dictated by the ocean currents. Sure, it may have warm periods, but the swirl of ocean water around the continent is what makes it cold. Only tectonic drift would bring it out of it's iced state.

But your post seemed to imply that Antarctica was warm 20,000 years ago. It wasn't.
Warm enough to live for a little while in the summer?

No. Your "ruins", aren't.

To say that the whole idea of an ancient but advanced Antarctic civilization is stupid is pretty closed minded when you consider that nobody knows what's under the ice or how long it's been since the continent had a temperate climate.
Yes there's no evidence currently because how could it be found under all that ice?
Mainstream human history only accounts for roughly the last 10,000 years. That's the blink of an eye for a planet that's 4.5 billion years old.
