I am playing around with materials in blender cycles, and for some reason my mesh is brightly lit with no lamps in the scene. ambient occlusion is off and I tried restarting blender. what is going on here?

$\begingroup$ hello, please show your Shader Editor, maybe you're using an Emission node? $\endgroup$– moonbootsCommented Apr 9, 2021 at 3:18

The World Background itself (grey) is also a source of lighting. To remove its influence, change the Color to black in the box on the right, or set the Strength to 0
This can also happen if you forget to connect your material to a shader before connecting to the material output:
This example just uses a Diffuse BSDF - note that despite the object no longer "glowing", it is still lit, even though there is no light in the scene - that is from the World Background as mentioned at the top:
