Passage: In August 2012, he made his European debut for the club, coming on as a substitute in a UEFA Europa League qualifying match against Gomel, replacing Joe Cole in a 0–1 away win. The following week, Sterling scored his first goal for the senior team with a first-half strike in a friendly against Bayer Leverkusen. On 23 August 2012, he started his first match for Liverpool in a Europa League qualifying match away to Hearts in a 0–1 win. He was given his first start in the league three days later in a 2–2 draw at Anfield to Manchester City. He played the full 90 minutes in the loss to Arsenal on 2 September, and the draw with Sunderland on 15 September, where he registered one assist and was named man of the match. On 19 September, Sterling was one of the group of teenagers that travelled to Switzerland to play Young Boys in a UEFA Europa League group match. He replaced Stewart Downing in the second half as Liverpool won 3–5. On 20 October, Sterling scored his first senior competitive goal for Liverpool in the 29th minute in a 1–0 league win against Reading with a strike from the edge of the box.

Passage: The first inhabitants were the Ahrensburg culture (11th to 10th millennia BC), which was a late Upper Paleolithic culture during the Younger Dryas, the last period of cold at the end of the Weichselian glaciation. The culture is named after the village of Ahrensburg, north-east of Hamburg in the German state of Schleswig-Holstein, where wooden arrow shafts and clubs have been excavated. The earliest traces of human occupation in Norway are found along the coast, where the huge ice shelf of the last ice age first melted between 11,000 and 8,000 BC. The oldest finds are stone tools dating from 9,500 to 6,000 BC, discovered in Finnmark (Komsa culture) in the north and Rogaland (Fosna culture) in the south-west. However, theories about two altogether different cultures (the Komsa culture north of the Arctic Circle being one and the Fosna culture from Trøndelag to Oslofjord being the other) were rendered obsolete in the 1970s.
