The link didn't work for me. What's the jist of your argument? Why don't the constellations jive with the past? Sometimes as you know science and this show don't exactly jive, the show comes first, as you observed with the Earth that showed up at the end of Season 3.

If it's the future, what I can't understand is why Athena, an ancient goddess, is suddenly a goddess again, and so on with the other Greek gods?
