Heh! You don't have to agree and I respect that... but you DID ask.Sorry. Point 2. I don't think a species of star travel would hang around watching a bunch of insects.
That is anthropomorphism run riot.
Not sure we've "cured" enough, just yet.Sorry folks. The ridiculous increase in population has now made you prime destination for a new butchers shop.
I can think of two very good reasons why Aliens have not visited earth. One is that they do not exist. No life - of any kind. Life is far, far too complicated to be spontaneously generated. Secondly: There is no physics for faster than light travel so giving us thousands more years to work on it will not find it if the science is not there.Since Roswell, why hasn't one civilian in the whole world taken a photo of an alien, a crashed alien space craft, or other hard evidence of their existence. What say you ?
. . . . . . . . . and these robots could of course also collect food to bring home to the butchers. Could explain mysterious disappearances, in which case we may be lucky and not found to be very palatable.At the risk of derision I will stick my oar in (!)
Lets say that we develop Quantum travel of some kind that instantaneously allows the presence of an object in two places simultaneously. Would we send our best, bravest humans... no, probably endless robot probes, and the primary mission would be observation and data collection (with the odd selfie for proof of concept and for the sceptical) rather than blowing things up and pillaging.
...although we historically have a tendency to crash our probes into things either by mistake or design.
Maybe the proof we seek in the original question will come when they make a mistake?
dfj - " I really doubt any aliens are going to want to fool around eating life from earth. Taking a few samples of likely eatables from various locations would quickly tell them that everything is loaded with Persistent Organic Compounds like PCB and DDT, etc. and a lot of methyl mercury, arsenic. etc. "Cat, I really doubt any aliens are going to want to fool around eating life from earth.

It seems likely that these nasty chemicals would be avoided by aliens no matter how sophisticated they are. If they are smart enough to get here with or without robots, they would be sure to look elsewhere for healthy food! Surely there are many other planets without the human pollutants as a food source.
If they hung around at all, it would likely be due to some entertaining aspect(s) we do that they really appreciate. Surely humor is one of the highest aspects of intelligent life! Reminds me of Billy Pilgrim in Vonnegut's Slaughterhouse-Five, where aliens, the Tralfamadorians , kidnap him and a Hollywood starlet and put them together to mate. I believe voyeurism had something to do with it. They could be just like many humans, big on watching other people (and other things) do that sort of stuff.
And I remember something about crop circles. Oh yes, didn't Led Zeppelin put out a compilation of LPs with crop circles on the cover? Now anyone suggesting there are aliens masquerading as humans and they are among us would certainly consider Led Zeppelin prime candidates! Certainly their music is out of this world.......
The notion that we (on Earth) are the only life in the entire universe is rather arrogant, regardless of its origins (how we got here). Just because we have yet to find it, does not mean it doesn't exist.There are no aliens and FTL travel is not possible. How's that for simple answers?
The spontaneous development of any life, let alone intelligent life, is complex beyond calculation. It just won't happen except as described in one ancient book which most people are so falsely proud as to discard its truths.
Finding a suitable planet is also a lost cause. Even with thousands found, none are remotely suitable for life. Better information is forthcoming and many more planets will be discovered with more refined instrumentation but I think the same answer will apply. For life on earth we seem to have accepted a circular argument which by logic can't be true. That is, that the unsuitable planet, earth, was made suitable for life by life, such as algae. Mathematics will not accept that kind of logic.
"Us" is at the top of the food chain and a trap for all the pollutants.Are you including us in that?
COLGeek, you forgot to mention Earth being the centre of the Universe and, of course, that it is flatThe notion that we (on Earth) are the only life in the entire universe is rather arrogant, regardless of its origins (how we got here). Just because we have yet to find it, does not mean it doesn't exist.
Our time as sentient beings is still but a blip of time on the cosmic scale of time and and space. The vastness of space alone could very well ensure we never know if we have neighbors unless they stumble across us.
