link recent post list to the original post

Hello!

My website for the following questions is:
https://www.loveleannekimberley.com.au

I would like to link each of my recent posts links (under the About Me widget on my home page) to connect to the original post. If you click on the links in my recent posts link they lead to a page that says “oops page not found”.

Do I need to create a separate page/menu with all my posts? If so, how can I create a separate page/menu with all my posts so that is NOT visible on the menu bar?

And last question – If I set up a hidden menu with my all my posts will they still be linked to google searches or will this decrease my traffic?

Thanks for helping with so many questions!

Cheers, Leanne
