ha! Thanks for the biology recap! My point however is how the bacteria "learned" to absorb that information and change. Each tiny bacteria is what like hundreds of millions of DNA coding? The coding is almost like an AI that can process that information. A tiny little computer that can evolve based upon what it learns? Don't you find that incredible? Now couple that with every organ within a human body. Literally a universe in itself.
