As the log mentions, the request came from google. So someone googled something and your old link showed up, which they clicked on and it will produce a 404.
When recreating an existing website where the url structure changes, it's usually best to have redirects in your .htaccess or something mapping your old urls to the new equivalent so the old content can be found on the redesigned site. If you don't, when people search you and find an old link they will get a 404 and move on the the next site from the google results. Or, you have to wait until the old links fall off of google and your new ones get cataloged. Sitemaps can be helpful with this as well.
