Utter tosh, there is no way that anything built on this planet could move and manoeuvre the way they did and although I'm a believer in God I doubt I saw two Angels dancing in the sky either so its the off world solution for me it being the only plausible explanation.
Anyone see the pictures this week from Mercury? An example of humans using technology to explore off world, I'm sure other races on different worlds do exactly the same only with better kit.
That makes sense. One of the world’s preeminent astrophysicists, Carl Sagan, believed that “the interest in unidentified flying objects derives, perhaps, not so much from scientific curiosity as from unfulfilled religious needs.”
Andromeda, the nearest galaxy to the Milky Way is 2 million light years away. This means that if there were aliens in Andromeda, it would take them longer than 2 million years to get here. The Andromeda galaxy is considerably larger than our galaxy. If life were common in the universe, there should be many times more of it in Andromeda.
We have been sending radio waves for less than 100 years. It will be another 2 million years before those signals reach our closest neighboring galaxy. They don't know we're here. The search for extraterrestrial intelligence (SETI) has extended out to 40,000 light years from earth (in comparison, the galaxy is 100,000 light years across) No signal from any extraterrestrial stellar system has ever been detected.
Recent scientific studies demonstrate that the universe is much less hospitable to life than it would seem from our unique Solar System and planet. A large proportion of our galaxy is uninhabitable. Parts of it would not even be expected to produce rocky planets. The highly unlikely collision that produced our large moon prevented the earth from being a water world. It also ejected the majority of our primordial atmosphere, which prevented the earth from going through a runaway greenhouse effect similar to what happened to Venus, our sister planet. Finally, our Solar System is unique in that it has large gas giants located only in the outer regions. Other systems discovered have gas giants located either near their star or in both inner and outer regions of their planetary system. The presence of gas giants near the star would eject any rocky planets from orbit. The presence of gas giants in the outer region of planetary systems is absolutely necessary for the survival of advanced life forms. Without Jupiter, the number of catastrophic collisions that the earth would experience would be at least 10,000 times greater. So instead of suffering massive species extinction events every 100 million years, the earth would experience these events every 10,000 years. Only bacteria and other simple life forms would be able to survive this kind of bombardment - no advanced life could ever form in the vast majority of planetary systems. These problems indicate that there would be no more than 150 advanced civilizations within our galaxy - and, more likely, we are completely alone in our galaxy.
It is not possible to travel at speeds greater than the speed of light - the physics of the universe prevent it. Second, traveling near the speed of light is impractical for biological organisms. Collisions with particles even the size of a grain of sand would be catastrophic. An even worse problem is that the light from ordinary stars would be blue-shifted all the way to the gamma end of the spectrum when traveling near the speed of light. These gamma rays would destroy all biological life - even if it were in suspended animation (if that were possible). In essence, these problems would restrict the speed of travel to well below the speed of light. The most optimistic estimate for the presence of extraterrestrial civilizations would put them 2000 light years apart (google Drake Equation). With no intermediate habitable stopping points, space travel over this distance would be impractical. So, even if we are not alone in this galaxy, it would be highly unlikely that any extraterrestrial civilization could have visited us.
