Hi, I would say it was simply an opinion or a speculation of how the world began with people, or how the Earth was filled. There is no scientific proof of other people being created or evolving into people. The Bible itself talks of two people that are responsible for human live. We have fossils of humans we have DNA of humans, but they are complete there is no proof of changing from animals at all. We have DNA that tells us that there is no slow evolving in genes at all. People have Human DNA or Animals have DNA, NO mixtures.
