I'm sorry, you're talking about life existing on earth before human beings?? E.g., bacteria, plants, animals, etc.? That isn't a matter of solid fact, as far as you're concerned?
Are you a creationist? Even the Bible describes life existing before Adam and Eve. << Judy, For me anything that's not scientifically proved is speculation. However, being well-documented doesn't mean that it's scientifically proved. >>
