-1 for now.
2 years is a huge gap in time for a DarkRP server, and things have changed. Some of the rules, punishments, community members and attitude. To be staff, you definitely are going to need to see how Aether is now as it's very different from 2 years prior. On top of that, coming back, playing for a day, and then making an app is too early. We wanna make sure you are consistently playing prior to the creation of your staff app and during the application period. I myself believe our only interaction was the event that was hosted a day prior to my response.
Your app is very lackluster as Vetes said, however these are things you can learn about as you get used to being back. It's nice to see an older player returning, just stay active and touch up on the new rules.
While none of your rule answers are incorrect, they lack some details that would help us understand how far your understanding of the rules go.
Regarding your activity, as Enzo points out, yesterday appears to be your first day back on Aether after 2 years. It's best to be relatively established in the community (forums, discord, in-game) before applying.
If you're able to be active, get to know people (and let people get to know you), and stay out of trouble you could very well have a shot but for now my opinion is -1
Good luck!
