Antibiotics like u, r created by the Creator.
Nothing on this earth evolved.
Man has made nothing, man only takes what is already on the earth and mixes things together.
Although i don't believe in evolution some Creationists do.
Some believe that between the Spirit of God hovering over the face of the deep, and the earth was void and formless was millions of years. That there was another earth made, and destroyed only to be rebuild with man.
I don't quiet understand it, but there it is.
I also believe penicillin that was formed from mold. True, mold was already here, in bread. It is a life form.
