I'm getting ready to install a ceiling light and run power off my light switch. Is there a way to tell if the wire in the attic is supplying power to the switch or coming from the switch?
You will first need to follow the general direction of the wire in the attic. See where it is dropping down into the walls. Also, use a multi-meter to determine what wire in the switch box is the HOT wire and which one is the feed to the existing lights/outlets on the switch. By doing these two things you should be able to assess if the attic wire is the HOT or FEED to the other lights or outlets.
I never seen a Greeny Wire Nut or a copper crimp ring i will have to look online to see what they look like but to my understanding different localities have different rules i know in school we use a yellow colored wire nut for two wires when splicing and a red one for 3 or more splices
Yes. Also, though not shown in here, you may want to tie the two grounds together using a Greeny Wire Nut, or a copper crimp ring, before attaching one of the bare copper wires to the wire nut on the outlet.
the wire number might be smaller but the actual thickness of wire is bigger meaning a 12 is thicker than 14 and a ten is bigger than 12 i dont know why they do it that way for example i have 6 gauge jumper cables for my semi real thick

so both bare wires get spliced and then pig tailed to connect to the ground screw ?

The smaller the wire size the higher the amperage is that how it works ?

Yes, for example a 14 gauge wire can support 12 amps, and a 12 gauge wire can support 20 amps.
