[Hoot Gibson]

I saw a UFO, along with everybody else living around Columbus, OH, in the mid-60s. It was a very high altitude object that was brighter than Venus in the evening sky and nobody ever determined what the object was. However, I am very skeptical that we have been visited by aliens.

In an era where almost all adults and most children have mobile phones with high resolution cameras, it seems unlikely that if aliens were here, then we would have no clear photos of them or their flying vehicles. It is far more likely that robotic probes sent by aliens and controlled by AI would be sent to Earth.

I will remain a skeptic until human scientists show that they can get around the interstellar travel obstacle of the speed limit of light.

The question of whether there is intelligent life anywhere in the universe besides planet Earth is entirely different than the question of whether aliens are among us. I find it extremely likely that there are at least millions of alien civilizations scattered throughout the universe.
