I am afraid we have not been visited. I do think that there is intelligent life. I also think that the likely only method of travel to overcome the distances involved is manipulation of space-time. Travel at near light speed would require ships containing multi-generational populations with an extremely varied gene pool. In addition, the social/psychological impact of leaving the home planet would be enormous. We have 7+ billion here and look at the destructive nature of humanity. Compress that population down into say 10,000 people in a very small, relatively speaking, space and the odds of destruction, imo, skyrocket.
We have no way of knowing anything about other life forms. That being said we inevitably make the assumption that they are carbon-based, require oxygen to breathe, water to drink and what we consider food to eat. We humanize them because we are human.
Beyond that, technologically advanced species would, again, imo, either go out of their way to be undetected or they would think us unimportant. As beneath them as ants or insects are beneath us.
As for eye witness accounts? Unreliable. Do I think that people who claim they have seen something are lying? No. I think that they believe it. Which is not the same as having seen something. Was Fatima real? I have no idea. In the end it does not matter.
