Two messages, one at 5:12 pm and one at 5:13 pm, were left on my answering machine Thursday (I think the date was August 19). After listening to them many times, I believe they are two different messages, left by two different "voices."I'm submitting this report and a digital audio recording of the messages because I believe they are connected to UFO sightings I have been experiencing in Angel Fire, New Mexico. A couple of years ago, I recall hearing similar sounds on an Internet site (sorry, don't remember when or which site) which described them as being made by extraterrestrials.The audio recording was made by holding a digital recorder near the answering machine on which the messages were made. I consider the recording to be about 98%-99%% as clear as the original messages (which I have retained on my digital answering machine).My Caller ID recorded the phone number, which is not included in this narrative (but which will be given to official investigator). If the reverse-number service I accessed on the Internet is correct, the phone calls were made from a land line in southern California.
