Like all words are made up of different combinations of the 26 letters of the alphabet, everything in the world is made up of different combinations of the 118 elements of the periodic table. When scientists can shake a box of letters and come up with a novel, I'll start to consider the theory of evolution. Of course when they do it they will have engineered it (shaken the box) so the results would be invalid. But so it is with "origins"! Very devout followers think of it as 'science' but one doesn't have to dig very deeply to find it really isn't, but is more like assumptions built on assumptions, therefor it's speculation, and a belief.
