Just to address your argument that the Earth is moving away from the sun, it's actually TRUE.

But how fast are we moving away from the sun?

"If we assume that the Sun's rate of nuclear fusion today is the same as the average rate over those 10 billion years (a bold assumption, but it should give us a rough idea of the answer), then we're moving away from the Sun at the rate of ~1.5 cm (less than an inch) per year."

To be fair, another source puts it at 15 cm per year but with one astronomical unit being 149,597,870.696 kilometres, that's not really significant either.

In fact, in a single year, our distance from the sun actually varies by ~5 million km.
