I’m really not sure if I understood the question, but figured I’d suggest some links to read.

no no i just want to add index.html to show in front of wordpress (index.php)

Move your WP to a subdirectory/subdomain, have your index.html as your main page and point to the subdirectory/subdomain for your blog.

hmm is the index.html will be infront of index.php and next point link to index.php

move the page is not so simple , it is a big page and the solution is not so good
