In alleged encounters with alien life, one percentage of five leaves some trace behind, such as burnt ground, footprints, powdery residues or metallic fragments. One group of ufologists studied thousands of cases and came to the conclusion that there were four main categories of extraterrestrial existence; small humanoids, experimental animals, humanlike entities and robots. However, Hilary Evans of the British UFO Research Association admits to the inadequacies of all findings and testimonies. Some UFO witness lie, either deliberately or unconsciously. So, with little more than the word of an apparent eye witness to consider, evidence for the existence of alien life forms is far from conclusive. Who knows, perhaps somewhere in this cosmos, another species is deliberating on the existence of the Farhling
