Don't know about AIDS, but it's more likely that it's a mutation caused by compulsory hepatitis vaccination in Africa. Why should it be designed against black people, when white people can get it just as easily?
Because they did not expect for it to extend that much.

No, I don't believe AIDS was created. Dunno, maybe, there are reasons to believe it was, yet no evidence. It's an interesting theory though, I love conspiracy theories, not because I believe them, but because I find them very curious, and some even have sense. It's still fun to read, along with all the spiritualist stuff and ghost stories which I don't believe at all. Not bad to kill time though. It also gives some ideas for stories to think up when you are bored in class.
