I have an 08' camry V6 with 85,000 miles on it, yesterday the battery light came on. I went to autozone and they charged my battery and tested it, Battery was at 12.6v with the car off and 12.1v with the engine turned on. Pretty sure my alternator is dead, but I'm wondering if there are any other possible causes or ways to fix it without replacing the whole alternator. I had just enough charge to make the 15 minute drive home. I haven't taken my engine cover off and really messed with it yet, but I can see the belt is fine, pulley is spinning and it's not making any strange noises.

It's most likely the alternator.
Either get it rebuilt by a local rebuilder or replace it with a Reman Denso replacement. You want to make sure you get one that has the OAD (Overrunning Alternator Decoupling) pulley installed. An OAD pulley is like a special type of clutch pulley.
With that said, you need to diagnose the alternator output. A battery light could be caused by a number of issues and replacing the alternator may not even be the fix.
You need a volt meter to check voltage at the battery, alternator output, and cranking voltage at the battery. Those can point you to a problem in the battery, alternator, or starter.
Additionally, you need to make sure you don't have a parasitic draw causing your battery to die when you park the car.
You can check that too. Watch these really good videos for how to diagnose problems related to the your issue:
