Yes, there are people who believe in Cthulhu as a fictional deity created by author H.P. Lovecraft. These individuals may be fans of Lovecraft's work and enjoy the mythos surrounding Cthulhu as a form of entertainment or as a way to explore themes of cosmic horror.

The first volume of Cthulhu is "The Call of Cthulhu," a short story written by H.P. Lovecraft and first published in 1928.

H.P. Lovecraft never provided an official pronunciation for Cthulhu in his writings. However, he did mention in a letter to a friend that the closest phonetic representation of the name would be "Khlûl'-hloo." This suggests that the "th" in Cthulhu is actually pronounced as a guttural "kh" sound, similar to the Scottish "loch." Therefore, the correct pronunciation would be closer to "Khlûl'-hloo" rather than "kuh-THOO-loo" as it is commonly pronounced. **
