Do you believe in other civilizations and UFO existence? I do and see no reason to be dubious about it! Our human civilization is so young and weak; we have so many inner problems on Earth like poverty, delinquency, discrimination, etc. We are so dependable on natural cataclysms. So how can we dare to imagine that humans are the only sentient beings in the Space. I think that such an approach is unacceptable and wrong. Just imagine the dimensions of the Space, the number of stars and planets around them. Just in our galaxy "Milky Way" there are over 150 billion stars. And consider that the Sun is very small star in comparison with most of them! The other side of the point is that the aliens may have reached such a level of technological development that became invisible and intangible for us. The other civilizations may also exist in the parallel world, so we can't find them too. As for UFOs I believe they are real, not just imitations or provocations. There are a lot of good photos,
