Hmm. You two are forgetting that Humans ARE part of evolution, and thus any selection they do is natural selection. We're the dominant species, and as such we are part of the natural selection process. Our "artificial selection" is just part of the whole thing. Thus, Evolution happens whether humans guide it or not.
Aha, but the whole debate began about evolution in a game. If we as the player influence the creatures in the game, then we are not part of the evolution, nor part of their universe. Therefore, the game is not simulating actual evolution in it's pure form.
Anything we do to creatures around us is still evolution taking it's course. We have evolved the brains and tools to edit other creature's genes, so genetic engineering is "natural". Plenty of parasites already influence their host's behaviour, and plenty of social insects (ants and bees and stuff) are capable of triggering mutations in their offspring. Not on purpose, but it's the same thing.
The part where humans do all this stuff on purpose is just because we have evolved the brains to do it.
Long story short, you cannot perform unnatural selection inside our own universe because "unnatural" is a subjective term, it just means "by humans". Any form of selection caused by someone outside the universe (a game, for example) is unnatural and thus not pure evolution.
Also, I don't get how you can possibly despise official science in itself. You can despise certain types of scientists, or the way media treats science, or how some branches of science waste money on seemingly unimportant fields.
There are carploads of people out there challenging science every day, and they often fail. And when they don't fail, their new theory is challenged again by other scientist. Personally I think that medicine, technology and all that jazz work a little too well for science to be so fundamentally flawed that it has to be despised.
It's admirable that you like to think for yourself, but going "Oh, but I don't like official science." when your views are challenged by well-documented scientific theories that withstood every challenge thus far is a bit silly.
