What is the Dulce, New Mexico Base?

Dulce Base is a subject of conspiracy theories, alleged to be a secret underground facility under Archuleta Mesa near Dulce, New Mexico, where it's claimed humans and aliens collaborate on various experiments. Stories suggest it's a multi-story complex involved in genetic research, mind control, and extraterrestrial technology, with tales of battles between humans and aliens occurring in the 1970s. Despite these claims, no concrete evidence has been provided to confirm the base's existence, leading it to remain a popular topic among ufologists and conspiracy theorists.
