if i add a light to a comp it will light up the 3D layer that is stacked underneath it.
When I move the light position to be behind the 3D layer, why doesn't it backlight that layer creating a halo like it would in real life?

Two reasons:
1) AE cameras can't see AE lights, even if they shine straight into the camera. It sees the light that falls on 3D layers, not the light itself.
2) Backlighting is created by light falling on 3D surfaces: shoulders, head, etc. If your 3D layer has no z-depth, the light has nothing it can fall on.

Halo as in reacting with the atmosphere?

There is no "atmosphere" in AE - though you might be interested in the plug in LUX from Trapcode, which might help you achieve the effect I think you are looking for. It makes AE's comp light visible.
