delete pre-installed URLs from theme

My website is http://6wordadoptionmemoirs.com/

I used a theme and it created a lot of URLs on my website that I don’t want. For example: http://6wordadoptionmemoirs.com/2015/11/14/the-photography-advice-i-give-every-time/

How do I either delete them or redirect them without having to go through each of them individually?
