There was a time when there was lush growth of vegetation and that was required to change the texture of the earth, to prepare it properly for the coming guests, that is human beings. And that could not have happened if there were not huge animals created who could devour all the lush green growth at the same rate and at the same speed.
Otherwise the whole plant would have to be devoured. We didn’t really know where to get such animal species. The dinosaurs did that work. They converted their energy into fresh energy, bones and things. They were ultimately buried in the ground to resist consumption. It’s such a wonderful machine being to depend on cause and effect and things. Very complicated affair. But whatever you saw, it looks very beautiful when organized.
