Kickstart is just extracting the backup archive. You are looking at the restoration script which is part of the backup archive itself.
The problem you get right now tells me that you have not filled in the "Site address (URL)" field in the previous page (Site Setup). Please retry the restoration, remembering to enter your site's address (https://kreativ-ev.de) in the "Site address (URL)" field of the Site Setup page.
