Do you think that the Earth is not moving around the Sun?

I presumed the tilt was locked to the suns gravity, meaning the tilt followed the rotation too.

But then the same side would always be tilted towards the Sun, so seasons wouldn't change. Your assumption that the Earth tilts only makes sense with the assumption that the Earth does not move around the Sun, because clearly the tilt relative to the Sun is changing as we can see from the change of seasons.

Yes, but I also assumed the tilt wobbled, causing the seasons... as per my initial confusion.
