You need to do a little more reading about viruses before you decide that one's a man-made, conspiracy-driven creation. For one thing, it's much older than you realize (read the link below), and it pre-dates the days when virus-engineering was even a possibility.
AIDS origin - Wikipedia, the free encyclopedia

Scientists know how viruses like HIV begin in the animal population, and they're fairly certain that particular one originated in primates. If you learn a bit more about viruses, you'll learn that the most deadly ones we know originate in animals (influenza, bird flu, Spanish flu, smallpox) and mutate until they're able to make a jump to humans. If HIV were a human creation designed to annihilate an undesirable portion of the population, then why have there been such government-supported advances in the medicines that treat it? Why would the governments and scientists even have bothered?

AIDS: Man Made Virus Last night I was with some friends and we were all sitting around the bong and we started discussing how the U.S. government created the AIDS virus. I did some independent research on this "theory" and it started making more and more sense. Turns out the U.S. government created it in the 70s under the Nixon administration. Their intent was to create a deadly virus that could control population, kill off less desireble people in society (such as the poor, drug addicts, gays) and save america Rating: 5
