This logical proof also explains why all mountains, which we know result from natural processes, are essentially identical chemically. (What? What do you mean their not?) Well then, it does explain why all the planets in the solar system, which we again know to result from natural and well understood natural processes, are essentially chemically identical. (What? You’re telling me that the planets also have a lot of chemical diversity?) Wow, it seems that natural processes produce a great deal of chemical diversity. But that doesn’t apply to life forms. Apparently, the earliest life forms included one type that was somewhat more survivable than all the other forms, and that life form then scattered all over the 200,000,000 square miles of early ocean and ate all the other life forms leaving no trace of their existence.
The only time we see a high level of uniformity in the chemical and morphological makeup of things is when those things are man (intelligent) made.
