[Theme: Origin] | Removing author?

Hi, I’m running the Origin theme on my (very very new) site at https://aysha.us. Was wondering how I’d go about removing the “by author” displaying by each post. (I do want to keep the date, however.)

I’m assuming I’d have to change something to a display: none somewhere or another…so, please explain it to me like I’m five.

Any help you can give would be appreciated!
