Created a new Page and it's now my "Home" page. All pages are now the new page?

Hello-

I created a new Page and after editing for a few hours, it seems to be *every single page* now (including my Home Page). What is weird is that Home shows 109 revisions (in the WP edit page window [outside of TagDiv]), and even reverting back to older versions does not change the home page back to it’s original state. The new page has 8 revisions. So within WP it seems like my original Home Page is still “there”, but trying to edit it brings me to the new page within TagDiv. Now everything on my site is this one particular page. I’m pulling my hair out trying to figure this out. Anyone have any insight as to what may have happened? Thanks!

http://www.ultralightnerd.com should have this layout:

Home should be multiple sections with posts, social media side column.
The new Page is the Ultralight Backpacking Gear List 2024 page (direct link: https://www.ultralightnerd.com/index.php/ultralightbackpackinggear2024/).

Heh, never mind! Figured it out. In the new Page I added all elements to the header and not the content, hence why it was showing up on every single page. Case solved! Thanks!
