Then providing a source for this claim won't be hard, will it? And if it's "widely known," then the details shouldn't be too hard either: where it was constructed, possibly who was involved...?
I love a good conspiracy theory as much as the next guy, but the idea that an extremely fast-evolving organism, with many analogues in other species (FIV for one), was created by humans with the limited technology of the late 1970s just makes me laugh. So please, prove me wrong. Show me a remotely reputable source that says "AIDS is man-made." Not "AIDS might be man-made" or "is AIDS man-made?" but "AIDS is man-made." Something with some internal support (citations, etc) would be nice.
This is Tilted Paranoia, granted, but even here you don't get to make claims like "It's widely known that..." without providing at least some evidence to prove that what you claim is widely held is, in fact, widely held.
