But still, why would alien lifeforms even have eyes? Perhaps they wouldn't be using the same spectrum we do... And again I say, perhaps they wouldn't even live in our 3 dimensions.

yes but it sounds like your saying theres only one kinda alien out there.. i'd say theres tons. and ones as you speak of that dont use the same spectrum or didnt live in the '3 demension' the way we do... Would they be the the ones most likely to visit earth? or would it be more likely that a species out there that evolved on a simular planet be the ones that visit?
im sure there are things out there that we cant even imagine, but you gotta think that ones that would phisically visit earth would be somewhat more likely to of evolved simularly then what your saying.
about the 2 eyes, i had read before about why creatures have 2 eyes, doesnt it give you depth perception or something? which is why animals and people and even fish alike all have 2 eyes. but they could have 1 or 3 or none.
and even if a alien had 4 arms, i'd still say its humanoid. it would still be simular, i dont think an alien is going to look exactly like us.
but you keep saying why would 'an' alien have 2 arms and not 40 and things, but why do you say an alien? maybe there are some out there with 40 maybe with 2, maybe with none, i think theres gotta be countless ways to have evolved into an intelligent life form out there.
its even possible to me to think that maybe out there theres a planet that the beings evolved exactly the same and look so much like us that we couldnt tell the difference.
But none of us could ever answer these things anyway, but its interesting to see how other people think
And as we all know from scifi shows and movies that everyone in the universe already speaks english :P
