inorganic chemistry - Why do silver nitrate and sodium hydroxide react to produce silver(I) oxide?

I did an experiment in class combining the aqueous solutions of $\ce{AgNO3}$ and $\ce{NaOH}$. I predicted that $\ce{AgOH}$ would form but it didn't, instead a brown precipitate. I found out it was silver oxide. But why does this happen?

I researched and found out that silver is a noble metal and is thus resistant to oxidation, so why is it oxidised in this case?

Also why is $\ce{AgOH}$ not formed? I looked at the reactivity series and apparently silver can't displace $\ce{H+}$ ions out of solution, is that why?
