It may, or may not be man made. There is really no way to tell, yet. However, The UN has said we have a population problem, as did David Rockefeller, and one of their long term goals is to reduce world population. We also know the Rockefellers founded and funded the "Population Council". They research the following, HIV and AIDS; Poverty, Gender, and Youth; and Reproductive Health. It's ironic that he would fund a group that is supposely for helping people when the rockefeller commission on poulation control said the following regarding population control in 1972. "In any case, no generation needs to know the ultimate goal or the final means, only the direction to which they will be found."
We also have Dr. Len Horowitz who firmly established in his 1995 book, Emerging Viruses, that the HIV virus which causes AIDS was introduced and spread throughout the majority of black populations in Africa via the World Health Organization (WHO) during their mandatory smallpox vaccine campaigns of 1976-1980.
Whether HIV was a man made virus is yet to be seen. However, all evidence is pointing towards Yes. Also, 11.5% of nurses in South Africa now have HIV, and numerous ones have said they did not have sex/share needles when working there. Just some food for thought there.
