Words Have Meaning

Changing the meaning of a word in the middle of a discussion is a propaganda technique commonly called bait and switch. You start out using a word in a way that seems to make sense. Then continue using that word in a different context, while leading people to believe the context has not changed. This is the way the word "evolution" is commonly used. It begins by using evolution to describe the emergence of a new species, or even just a change within a species. Everyone agrees this is observed. Then continue using the word "evolution" to talk about entirely new kinds of life coming into existence. Something that has never been observed.
