I am an atheist.
I believe in UFOs.
Do these two statements seem contradictory to you? Why? Just because I am a person that does not believe in a supreme being or a higher power, does that make me unable to accept the possibility of intelligent life existing outside of our own planet?
If you answered yes to any of the above questions, then you are wrong. Now, I can’t speak for all the atheists, only for me. So let me let you in on my beliefs. I have faith. I know that may come as a shocker, but it’s true. I have faith, but not in any higher power, or supreme being. I have faith in knowledge. Religion, since the dawn of man, since the time of cave paintings, before the firsts cities were ever conceived, has been a way to explain the unexplainable. Why does the sunrise each morning and set each evening? Does the sun god ride his chariot across the sky every day, and rest every night as the ancient Greeks believed? No, the Earth rotates on its axis as it orbits the sun, thus creating day and night, the year and even the seasons. The ancient Greeks didn’t know that then, but we know that now.
So, how does this explain UFOs?
Simply put, in my opinion, we have had too many sightings that have been recorded to say that we have no knowledge of UFO’s existing. Well, what about Moses, and the parting of the Red Sea, you ask? 
There is only one source that says that the event actually happened. The Bible, and I think the writer was a little biased on that one. If it had just been one hillbilly from Tennessee that was screaming about how these grayish guys with huge eyes took them aboard their flying saucer, OK, I wouldn’t readily believe him. But it’s not. There have been videos from all over the world showing flying craft that defy the laws of our flight. Recorded by people in the streets, from the windows of their homes, even from gun cameras on military jets.
They exist
I see no other reasonable explanation. Logic would be that in the trillions upon trillions of stars in just our galaxy alone, there has to be at least one other planet that has life on it. The odds that we are the only planet with life is so infinitesimally small. And the odds that one of those other planets is home to a species that has evolved the knowledge of interstellar travel before us are very good. More than one probably.
The belief that we are the only planet that has any life on it, let alone intelligent life, is so egotistical, that I would have figured only people who believe in god would assume that. I mean, he only created us, right? Atheists may be skeptical, but it is only about religion that we are skeptical. We embrace science and logic, not a myth.
