Now think about the whole universe developing similar to the development of a human embryo. Think of the development of a human embryo as a model for the development of the whole universe.
The model (a human embryo) is not a miniature replica of the universe. Instead, the model is believed to be nearly identical to the universe in concept. Each element or function in the model has a parallel element or function in the universe.
Computers are regularly used to model various phenomenon -- flooding along a river for example. There is very little, if any, resemblance between a computer and a river. But a computer can predict flood stages along a river based on rainfall on various areas of land that drain into the river. In a similar manner, human beings may have little, if any, resemblance to the whole universe, but the development of a human embryo can be used to model (to predict) the development of the universe. Embryos were programmed by The Word of God -- at creation!!
