Aliens??

So i heard the other morning on Bob and Sheri something about some spacecraft sightings in Texas..i thought it was really actually interesting because like its kinda weird to think that there are other ppl besides us out there they say that everyone has a twin in the world..well maybe there is another planet with everything like earth and thats where our twins are! I hope by the time we are older we will discover new things with the solar system that are unknown to us now..anyways what do u think about aliens? are they real? what do u think they look like?
