ggplot2 - Cant make t distribution with ggplot in r

Question

I have a large sample size (n=9000) and I want to plot this distribution with its confidence intervals.

Generally, I think I have to plot a t-distribution but I don't know how to plot it. Or is it because the high sample size, that I can plot a normal distribution?

How could I plot it with ggplot and how can I add a line wich emphasizes the mean and confidence intervals?

Thank you for helping!
