I suspect, if its the same as Blitz3D, your earth is beyond the camera range.
I'm pretty sure that because your sun object is scaled up x10, all positionentity calls are scaled by a factor of 10, too. Its been ages since I did any Blitz3D stuff so I could be slightly incorrect on this, but try increasing your camera range. I think it defaults to 1000, so change it to 2000.
