But when editing the theme select page, there is none:

Answer 1

The new template is a .php file in the same theme. You can copy the page.php file and change its name in the comments above and you will have your own template.
<?php /* Template Name: Имя шаблона */ ?>

Not this way.
Create a sample content file in the theme folder that is active.

<?php
/* Template Name: Some name*/

get_header(); ?>

<?php get_footer();
