A consideration about aliens

I have been reading the first two books on the "Space Odyssey" series, namely "2001" and "2010." I went to Wikipedia to check for some information regarding them and found out that the late Arthur C. Clarke created what he called an "orthoquel" to the stories, a set of elements that move on a paralel fashion, not directly related, to the original Odyssey. According to the Wiki entry for the Time Odyssey series, "not-so-benevolent godlike aliens start an endless mission to regulate the development of sentient life in the Universe, in order to prevent all other species from harnessing too much of its energy, which would only accelerate the inevitable entropic death of the Universe, thus rendering sentient life impossible at the end of the universe. Consequently, these 'Firstborn' are destroying all intelligent species."

Somehow the idea got me wondering about how it could relate to the UFO situation at present. As far as we know, no verificable contact with other intelligences has ever been made, and it would seem as they are either not that interested in us or are trying to avoid us. If so, and if we accept the existence of the UFO phenomenon as interplanetary visitations, then the whole idea of them monitoring us with friendly intentions has no sense, unless we are a subject of study on the same level monkeys and meerkats are to us, interesting to behold, but not worth the possibily of contact. Now, how about if we are being monitored in order to keep us in check, to see that we don't have access to technologies that could potentially endanger not just us, but some other species as well. So far, all our destructive potential has been focused on us (as species) and maybe someone wants to see that it remains that way.

Also, I have to expose another idea. Regarding meerkats an monkeys again, if we had a tribe of those animals suddenly developing a technology that would harm many individuals, like meerkats developing fire or flint weapons, and engaging in warfare with other tribes, would human naturalists intervene? Certainly not, that would be against the spirit of scientific observation. Maybe they would pick some corpses and save some live specimens for study. I think the same could apply to alien observers on Earth. Don't count on them to save humanity, just the spoils of war/ecological degradation/cosmic disaster. That won't make them good or bad, just plainly scientific.

Anyway, on a side note, I just found I have the original and complete soundtrack for "2001: A Space Odyssey" on a cassette tape that has been forgotten on my office desk for years. Maybe I should digitize it in order to keep it for posterity.
