Blog Page not showing older posts

Hello!
I want the blog page on my website to at least give an option to see older posts, but right now there is no option to see anything older than the most recent four posts.
I don’t know how to change this and I would really appreciate some help.
Thank you!

The site is running an Avada child theme if that makes a difference.
