Bongani Ndulula, Themba Zwane, Phumelele Bhengu and Mandla Masango got the goals for South Africa, before an own goal by Ramahlwe Mphahelele and another by Sami Alghulla made it two for Libya.
It was a one-way traffic throughout the match, with Amaglug-glug enjoying most of the possession, while Libya offering nothing in attack and showed tiredness towards the end.
Masango had a blinder for Amaglug-glug, and Bhengu, Ndulula, Kamohelo Mokotjo and Thandani Ntshumayelo kept the Libyans busy; an 8-0 scoreline would have been a better reflection of the match.
Coach Shakes Mashaba will be worried with his side conceding two goals at home going into a second leg in Libya in two weeks' time.
Ndulula opened the scoring for Amaglug-glug with a tap-in on 22 minutes, after Libya keeper Mohamed Abuckhres failed to hold onto a shot from Zwane.
Libya’s first chance of the match came on the 36th minute when Mohamed Elgadi shot was saved by Khuzwayo after Sibusiso Mxayana had given away the possession.
On 43 minutes Amaglug-glug went 2-0 up, after a fantastic piece of play. In a well-organised attack, and despite the box being crowded by the Libyan defence, Ntshumayelo spun a pass to Masango, and the Kaizer Chiefs man rounded the keeper brilliantly and unselfishly pulled the cross back for Zwane to slam the ball home.
After the interval, Amaglug-glug continued with their dominance and Bhengu increased the tally to three in the 51th minute.
He received a sublime cross from Doctor Mampuru and did not make a mistake, as his diving header beat Abuckhres.
Masango was rewarded for all his hard work with a goal in the 68th minute, when he played a brilliant one-two with Ndulula in the box before picking his spot and hitting home to make it 4-0.
Mokotjo kept the pressure up, driving a shot at the keeper a minute later. It was not a bad effort, but saved.
Mphahlele made it five goals scored by South Africans, but unfortunately for the Moroka Swallows man it was an own goal, as he headed the ball past Brilliant Khuzwayo in an attempted pass back to the keeper during a rare Libyan attack in the 71st minute.
Masango and Ntshumayelo took pot-shots from range, neither missing by too much, but the scoreline remained the same.
While the home side continued to push more bodies forward, Libya waited for the counter-attack and were rewarded when Sami Alghulla reduced the tally to two.
The Libyan players displayed some skill in the match, but the scoreline flattered the visitors, who were dominated by South Africa from the first whistle.
