Someone said that you don't have to believe in Guru Nanak's teachings but he is still real. This true? Apparently, There's evidence that he exists. Are there citations in the Qur'an that supports or denies his existence?

Guru Nanak is the founder of Sikhism and lived in the 15th Century. There is plenty of historical evidence that he exists. You do not need the quran to tell you this, a bit of research and looking at historical documents will tell you.
Guru Nanak is just the religious leader of a religion, that came after Islam, so the quran would not mention him as he didnt exist at the time of its revelation.
