The subject of extraterrestrial life always sparks heated debate between believers and skeptics. While there is always room for debate, some evidence is hard to dismiss. Stories of abductions are usually dismissed as delusions, and photographs are often considered feats of trickery. What do skeptics say in the face of physical evidence?

Since the 1960's, there have been over 3,000 documented Trace Cases (Close Encounters of the Second Kind). Trace Cases involve extraterrestrials leaving impressions in the dirt, breaking vegetation, burn marks into objects, and other scientific abnormalities that leave some sort of physical evidence. These cases have occurred in over 90 countries around the globe.
