Many of you have read stories about unidentified flying objects or UFOs. What exactly are (the/these/that/those) UFOs ? The most popular (reason/thought/explanation/cause) is that these flying objects are spaceships. Inside these spaceships are visitors (from/to/in/for) outer space or other planets. Their purpose is to (discuss/study/discover/catch) life on Earth. It is also believed that these (creatures/planeteers/people/things) are scientists and some of them have taken the (place/role/picture/form) of humans and are living among us ! Although many of the UFO (sightings/occurrences/appearances/comings) are difficult to explain, most of them can actually be explained easily. In most cases, it is (actually/thinking/thought/probably) that the observers made mistakes when they saw something flying over the sky. They could (be/get/had/have) mistaken a ‘runaway’ weather balloon or a small aircraft for a UFO. The light that they saw could well have been the (illusion/shining/deflection/reflection) of light from the ground to the clouds. (However/And/Although/Consequently), there are still a number of sightings (who/will/where/which) cannot be explained scientifically. So they will remain as (stories/talks/reasons/mysteries) until someone can find an answer.
