Then they would be wrong. You are confusing unexplained with inexplicable. The former means we don't know yet; the latter that there it can never be known.
Such exaggerations happen all the time; it is part of the human psyche to want to please by supplying what you think the listener wants to hear. A case in point was several years ago, when as an April Fool's Joke, the astronomer Patrick Moore said on BBC Radio 4 that Pluto would pass behind Uranus, causing the Earth's gravity to temporarily weaken, and the BBC was inundated with over 1,000 calls detailing "reduced gravity" events that simply never happened, including one lady who reported that she and her friends rose from their chairs and floated around the room. Similar to your tale, and not a grain of truth in it, either.
You're still assuming that any lifting took place, without any evidence to that effect. As to articles, certain books might be better, I recommend the following to start you off: "Why People Believe Weird Things" by Michael Shermer, and "The Demon-Haunted World" by Carl Sagan.
No; the accumulation or "ratcheting up" of what works by natural selection.
I don't really see what you're getting at here. Are you hypothesising, "what if certain tribes of humans had evolved in cultural isolation?", because if so, you only need look at the Yamomami of the Brazilian Amazon to see the results. If, however, you mean, "what if mankind somehow retroactively caused our own evolution" in the fashion of a certain Star Trek: Next Generation episode, then you're into fantasyland, and there the best rebuttal I can think of comes from Richard Feynman. When asked by a hippy type how to build an anti-gravity machine, Feynman replied that the best example of an anti-gravity device he could think of was the cushion on which the hippy was sitting! To use a quotation from Star Trek again, "Ye canna change the laws of physics, Cap'n".
No, nothing with a consciousness has to balance anything. You're assuming again; namely, that the universe requires a Creator. That's analogous to saying that everything in existence must have had a purpose. The universe has no purpose; it is just one slice, a cross-section, of the multiverse. No design required. The watchmaker is blind. The anthropic argument is bogus. It's akin to Dennis Thatcher who argued that there was no poverty in Britain, because he never saw any. What he's really testifying to is his lack of experience (his never seeing any poverty doesn't mean poverty doesn't exist; rather, it shows up his lack of experience) and his paucity of imagination. If this universe were any different, we wouldn't be here to marvel at how great the universe is. But the universe doesn't exist to suit our niche in it; we evolved to adapt to it. Were the universe greatly different but still capable of supporting life, we would still exist, but not in the form we have now. (Whether we were intelligent enough to realise this distinction is a separate point.) There is no one driving the car; it's just that the mroe anthropocentric we are, the more we feel there must be someone driving us. But it is very childish to assumethat because it feels like someone's driving, therefore they must be. See the difference?
