As a visa applicant, your task is to convince the UKVI examiner that you will return to your home country after your visit to the UK. The examiner will look for "ties" to your home country — things that would motivate you to return home — rather than violating the term of your visa, staying in the UK, and going underground in order to remain.
Things that suggest you would return home include (but aren't limited to) owning a home, having a continuing good job, having a spouse or children in the home country, having relatives in the home country, having investments or a business there, and so on.
You can't create a spouse or children, but family ties have some weight. The existence of your parents and other close relatives there should be included in your application. If you have no relatives in the UK, I'd mention that as well.
