You might want to focus a little more on the word "selection" here. Humans did not deliberately select a certain strain of flu and prevent the others from propagating. If they did, then that would be artificial, not natural selection. That's the difference.

So if human interaction deflects a genome in some direction or another that was unintentional that was natural selection, but if humans intended the exact same result, it wasn't natural selection? Let me point out that humans are a part of nature.

You're still not coming to the right understanding of the word "selection". Natural selection is what preserves a genetic change that has occurred; it's not what causes it.

That true only to the extent that automobiles are part of the natural environment.
