Some UFO's ARE from another planet.

Whether or not the universe is infinite or not doesn't entirely matter. It is seemingly infinite; with trillions of solar systems within several galaxies. Science has shown Earth is billions of years old. If the Earth is billions of years old, then there must also be planets and solar systems much older. In so many years, over so many trillions of planets, life had to have evolved somewhere to the point where the life forms became advanced enough to travel to different stars, and once a species has reached into the stars they become immune to being destroyed by a natural disaster such as a meteor. This would mean that their race would exist forever, with the only threat being another more advanced race tracking them down and killing them all(In that case there would still be other advanced aliens, and my point would stand.). Any race that exists for thousands or millions of years would probably be able to easily search for other planets containing life. Then the only issue would be about how they get here in the first place. Einstein believed it was impossible to go faster than light, but that doesn't mean he was right. Besides, I'm not even going to try to guess how they did it but for the sake of the argument lets say these aliens watching us know of some way to travel to other planets faster than light or perhaps they spent thousands of years travelling to Earth at sub-light speeds. It doesn't really matter how they do it though because if we knew how they did it we would already be travelling to other far off planets ourselves. So lets just take a look at some of the evidence that points towards it being technology over unknown natural phenomenon. - Many UFO's have evenly sized lights or an even shape. Things in nature are generally more uneven looking. - Signs of intelligence. Some UFO's have chased or flown next to aircraft for a given period of time. There have also been several documented cases where some UFO's have shot beams of energy at nuclear warheads and disabled them. - Most legitimate UFO's that have been captured on film appear to have a mass, and yet they still can hover without making noise or succumbing to Earth's gravity. Unless some military or government has had the technology to hover(without making any noise) and to travel faster than any of our fastest aircraft today for the past 60 years(Or much longer), and for some reason have kept it secret for the past 60 years, then the most simple solution would be that it is infact alien. The only other three explainations that seem reasonable are: Raptors evolved to the point where they could travel into space and avoided the meteor that killed all other dinosaurs and now they're watching humanity grow(Where are the ruins of the great raptor cities?), UFO's are actually time machines and we are being watched by ourselves from the future(You'd figure they'd be more careful hiding themselves to avoid timeline contamination though), there is a secret underwater Atlantian nation that has technology hundreds of years beyond our own and they don't want to make direct contact with the primitive natives. These three explainations really make aliens seem more possible, don't they?
