WordPress has two default post type called Post and Page. Post are displayed in reverse chronological order from latest to oldest on your blog page or home page. Each time you publish the post it will appear on the blog page. If you want to change the order of the published post, you can simply change the post published date.
On the other hand, pages are stand-alone content especially used for About Us, Contact, and Information pages. Pages are not repeated like the post and each page has its own content and use.

After Adding this Code:
In case of the post, you can just go to Screen Options and Enable the Excerpt to show excerpt field on the post.
