I usually don't deal with Ufo which stands for unidentified flying object. The reason why is because even though i do believe their is other life out there, i just don't see the evidence for ufo's that compelling. I am open however to any evidence for ufo's that can help shed some light on what they maybe. A lot of people believe ufo's are flying saucers, with little green people that use them. The material which i am going to link to right now, i have come across well searching through the internet.
Here's some of the material i have found
One of those sites is called ufoevidence.org
Here is some of the photographs
A video on youtube called Evidence- NASA UFOs.
I do find the one the videos on youtube with NASA UFO's to be the most compelling evidence for UFOs.
