Fact. There are many reasons to believe aliens exist. The universe is incredibly vast, with billions of galaxies, each containing billions of stars. It's highly likely that some of these planets could support life. Also, there have been numerous reports of UFO sightings over the years, although not all can be verified. Some of these sightings describe strange objects with capabilities beyond our current technology.
Fact. There are some ancient texts and carvings that seem to depict things that are hard to explain without the idea of alien visitation. For example, some Indian scriptures describe flying machines and strange beings that could be interpreted as aliens.
I think it's more likely to be fiction. Although there are some strange stories and artifacts from ancient times that seem hard to explain, it doesn't necessarily mean aliens were involved. Ancient civilizations had their own creativity and ways of thinking. For instance, the pyramids in Egypt were built by the great engineering skills of the Egyptians themselves, not by aliens as some wild theories suggest.
Fiction. There is no conclusive evidence that ancient aliens visited Earth. Most so - called 'proof' consists of misinterpretations of archaeological finds. For example, the Nazca Lines can be explained by the religious and cultural practices of the ancient Nazca people without the need for alien intervention.
I think it's a fact that aliens exist. Just think about how many stars and planets are out there. The odds of Earth being the only planet with life are extremely low. We've only explored a tiny fraction of the universe. And the variety of life on Earth shows that life can adapt to many different environments. There could be forms of life out there that are completely different from what we know. Maybe they're based on different chemistries or have different ways of evolving. So, based on all these reasons, it's very likely that there are other intelligent beings in the universe.
Fact. Recent scientific discoveries have increased the likelihood of aliens being real. For instance, the discovery of exoplanets has shown that there are many planets out there with similar conditions to Earth. These planets are in the so - called habitable zone, where the temperature and other conditions might be suitable for life. Also, the study of extremophiles on Earth has shown that life can exist in very unexpected places, which broadens the scope of where we might find alien life.
It could be fact. Some of these books might present evidence like unexplained sightings or abduction stories. However, there's no conclusive scientific proof yet. So it's also likely to be fiction. The books might be just for entertainment or exploring the concept of extraterrestrial life.
For the 'fact' side, some point to strange ancient structures like Stonehenge that seem difficult to build with the technology of the time. However, against it, archaeologists have shown that humans were quite capable of such feats through trial and error and the development of specialized skills. For example, the way the stones were cut and placed at Stonehenge can be understood as a result of the knowledge and tools available to the ancient people who built it.
Most likely fiction. The concept of being abducted by aliens is already in the realm of the unproven, and when you add something as strange as 'cocks milked' to it, it just seems like a wild and made - up story. We know of no alien species that would do such a thing, and it doesn't fit with our understanding of biology either.
