coming soon page

Basic question, but how do I change the home page? right now it says:

“Nothing Found
Apologies, but no results were found for the requested archive. Perhaps searching will help find a related post.”

I can change/modifythe other pages I’ve created, but when I go to the dashboard and “all pages”, it does not have an option for home page just “title” which can’t be modified.

I am not very technically savvy and am doing this on my own so any help is much appreciated.
