Yes: most mainland Norway ice was gone during the holocene climatic optimum (9–6 thousand years ago), and glaciers recovered since then (until approx the 20th century, when deglaciation started accelerating again).
The climate is varying in long cycles, and the deglaciation 20 thousand years ago (last glacial maximum) was driven by a spike in summer temperatures, and this peak has already long passed. Ice ages and interglacial periods have a certain momentum to them, so it takes more than just that to go back to full ice age..
No, it's not wrong or we wouldn't be finding 5K year old instruments underneath melted glaciers as this article's evidence shows. And ice core samples from Greenland and Antarctica support this.

Yes, the early Neolithic was warmer than modern era.
wrong: IPCC AR6 puts the warmest Holocene stretch (~6.5 ka) at about 0.2-1°C above 1850-1900. 2011-2020 already beat that

Whatever you put in the glacier the glacier gives back to you. Anything you leave there ends up at the bottom of it in the moraine.
