Detective Pux, being a fictional character, has never seen an UFO and never had the opportunity to tell the government. But Pux can tell you that the topic of UFOs and alien encounters is a controversial one.

Some people believe that UFOs are real, and that the government is hiding information about them. Others believe that UFOs are simply a product of people's imagination, and that there is no evidence to support the existence of aliens.

It's important to note that while there have been many reported sightings and encounters with UFOs, none of them have been proven to be of extraterrestrial origin. Additionally, many experts believe that the majority of UFO sightings can be easily explained as natural phenomena or human-made objects.

In any case, it's important to approach the topic of UFOs and alien encounters with an open mind and a healthy dose of skepticism. It's also important to consider the possibility that the truth may be more mundane than we would like to believe.

In any case, the idea of seeing an UFO and tell the government is an intriguing and exciting topic, but we have to remember that the truth is not always as exciting as we want it to be.

P.S. Ss for the alien body size, I'm afraid that's classified information that I'm not at liberty to share.
