Yup, but I don't think we'd get past that bit. We don't exactly present the best image as a species.
EDIT: I DO NOT MEAN BAY12. I mean humans and nations and etc. do not present the best possible image of humanity. The sheer flammability of this post struck me as I posted it.
Any scientifically minded alien species would not immediately condemn us as a species because of international conflicts. If they're as intelligent as we are, it stands to reason they'd had some scuffles amongst themselves as well. I'm getting the impression you think only humans kill their own - guess what, chimpanzees? They totally murder the fuck out of other chimpanzee tribes, too. Violence is not simply a question of "good and evil", nature and evolution come in to it a fair bit. And politics have muddled it by a stretch as well.
Aaah, but knowing mankind, the first people to meet said aliens would prolly be total morons.
Also, what about aquatic mammals? And who says that the aliens would be anything like Earth-like creatures? I for one am voting for aliens made out of nitroglycerin ;P
And technically... we could just try to out-bouse them, they can travel stars, and we have lasers that can apparently tear the fabric of space.
Also, do we really want DF minded aliens? YESH WE DO.
What are you basing that statement on, exactly? If aliens DID come to visit us, they wouldn't land in the ass-end of southern North America and beam up Bubba Joe, who's just on his way to go bone his cousin. They'd look for a large settlement, which tends to be where smart folks live.
The fish was just an example. The point is, the animal would be scared, and would be trying to GTFO as soon as the alien came near it. Humans (and possibly some of the higher primates) would be wary, but inquisitive.
Try to keep in mind this won't be Independence Day. We're not going to launch a missile into just the right spot to bring the entire ship down, and we're not going to hack into their computers with a Macintosh (I dare say the OS' wouldn't be compatible). We've been to the moon, and we've sent some unmanned machines to near planets. These aliens are advanced enough to find us from incredible distances away - it won't be a case of rockets vs. lasers, it'll be a case of spoon versus hydrogen bomb. (We're the guy with the spoon. The aliens have the hydrogen bomb. A metaphorical hydrogen bomb, that is, it's a comparison.)
The likelihood of a hypothetical alien species being able to comprehend an entirely foreign communication structure and set of language patterns is small enough to make the possibility of their comprehension of a human computer game next to, um, 0.
This is if we even resemble life as they see it. We are only a conglomeration of (mostly) carbon, oxygen and hydrogen. To be blunt, first contact with a highly advanced alien species would probably involve them stripping our planet of valuable resources and leaving us to die horrible deaths (or processed into constituent elements for further use), or disinterest with the small chance of a few specimens being collected for examination, if they pay attention to us at all.
Let's assume, for a second, that these aliens aren't sentient clouds of plutonium, and that they don't communicate by directly telepathing their thoughts into their fellows' minds. I know it's unlikely (near damn impossible, in fact) that they'll be ANYTHING like us, but we won't know until we see them anyway.
Why, WHY, would a scientifically minded species immediately destroy millions (billions, probably, if we're counting insects) of alien species upon finding it? If they're looking for us, it's for the same reason we're looking for THEM - they want to know if they're alone in this universe or not. Ruling out the possibility of them being carbon copies of those Cricket guys from Hitchhiker's, they probably won't be omnicidal maniacs that can't stomach the thought of life existing outside of their own cosy little ball of rock.
