At a recent archeological dig in Greece, the bones of what appeared to be a giant were hailed as "proof" of the existence of Nephilim as depicted in ancient texts. It was later proven to be a HOAX. People continue to search for the existence of supernatural beings.
According to the Book of Genesis, Nephilim are the "sons of God." They are also mentioned as giants in the book of Numbers. The interpretation of these passages has been called into question by scholars. There is no clear answer as to the meaning of the terms used. Commentary in subsequent translations of the Bible draw conclusions from books in the New Testament as proof of the nature of Nephilim mentioned in the Old Testament, but again there is no clear answer. Other ancient texts assign the term "fallen angel" to Nephilim and similar beings.
