Aliens - Are they out there? Have they visited us? And related questions

[Anomalocaris]

I am not assuming we are the first. But it is a different kind of narcissism to assume we or our planet warrants any special attention, or that any who came before us would be motivated in such a way that they would visit us.

Earth is reasonably suited to most of the life I am aware of, and earth has many resources, not to mention that our race is suitable for a number of forms of manual labor, with enough intellectual capacity to perform such reasonably complex tasks as language and science. I'd say we make good cheap slave labour, and there's 7 billion of us, and we have little difficulty breeding more. That we haven't yet been carted off by slave traders, and also haven't been exterminated for our resources and/or planet, admittedly makes me feel more safe in regards to the galaxy.

I heard an interview with an archaeologist who said he hears the arguments like that for Atlanteans and says "where is their garbage then?" That we just don't see anything in the archaeological record that can't be identified with one particular known historical group. If the aliens were here, either it was way before humans were around, or they were the neatest bastards to walk the face of the earth.

Strange that i interpreted that to mean that the aliens were all gay >_>

Earth is suited to most life you know simply because those life for which earth is not suited would either be extinct or never evolved. Aliens probably never had anything to do with the earths, so no need to suppose we or our planet suit them. While being slaves to aliens might be titillating to us, it may not be titillating to them, we eat a lot, shit a lot, talk a lot, need lots of water and air to stop from dropping dead and making a stinking mess . We can barely carry our own body weight, we lie around doing nothing like sacks of potatos for a third of each day, we can't crawl up walls, we can't breath water, we not good at thinking straight, we are fractious. If their body plan isn't like ours, which it almost certainly isn't, then they can't even use us for sex in a pinch, gay or straight. So We are generally not good for anything, and smart aliens with space travel technology can do better with gadgets.
