Reading some of the back-and-forth in the sunsets in EA thread, I started getting confused about possible light ray paths from the sun to the moon then back down to an observer on earth at around sunset. In my mind, surely the high incidence angle of light hitting the moon before it begins its path toward observers on earth would have an effect on the nature and timing of moon rise and set, because the distance between the sun and moon change in FET over the course of the lunar cycle. This is argued to be the cause for the lunar phases, which makes sense, at least on its own.
This brought me to look at explanations for the lunar phases and the moon tilt illusion on the wiki. EA is invoked to explain the different apparent angle of the moon's illuminated side to the apparent position of the sun. The illuminated side of the moon consistently points up and away from the apparent position of the sun.
What's not explained clearly (to me at least) is why the illuminated side of the moon would be pointed upward if the light that contacts the moon would, under EA hypothesis, be incident from the underside due to upward curvature of the suns rays away from earth's surface.
Thanks for any clarification.
