Moving post/entry meta on family theme

Hi all,

Not at all familiar with writing code so any help you can offer would be greatly appreciated. I’m trying to do two things:

1) I’d like “Posted on …” as well as ” Leave a comment” to be moved to the bottom of the post.

2) I’d also like to change the wording from “Posted on…” to read “Published on…”

For reference this is the site I’m referring to: https://www.tellingthroughstories.com

Any help you can offer would be greatly appreciated.

Best,

Sy
