Extraterrestrial life

[Gabu]

From all we know about the magnitude of the universe, it's extremely likely in a purely statistical sense that there is other life in the universe.  I would argue, however, that there's no reason to believe that this form of life is any more complicated or on any form of higher level than what is found on Earth, and therefore, that there's no reason to believe that aliens in flying saucers have been to Earth.

Pretty sure their is..but I don't believe it has visited here.

The surest sign there is intelligent life on other planets is that they have yet to visit here.

You stole that directly from Calvin and Hobbes.

I knew someone would get that and I suspected it would be you.

I never miss a Calvin and Hobbes reference.

No. The possibility of simple lime indays of antiquity or now is one which I often consider, but I doubt that intelliigent life exists beyond our planet.

I'm not entirely sure I understand this post... for one, what is "simple lime"?

I do not believe there is extraterrestrial life.

Care to go into more detail?  I'm curious why.

"Beam me up Scotty, there's no intelligent life down here!"

Indeed.

Quit attacking my bad spelling.

I had to.  It was in a comment on intelligent life.  Too good to pass up.

If you wanted to be really picky, you could also point out that that's a comma splice.

And all of this speculation assumes they are carbon based lifeforms. It's possible life forms exist in merely energy form, etc.

Well, assuming that they're made of matter, carbon is the most likely base for any living thing, purely because of how many bonds it can make to other elements.  The other items below it in the periodic table, like silicon, are also possibilities, depending on the gravitational properties of the planet (it would have to have a lesser gravitational pull for organisms based on heavier elements to be able to live).  I suppose that you could also make an argument that, say, a nitrogen-based life form would be possible, but it would be very likely to not be capable of being nearly as complicated.  Anything further to the right of that is simply not at all likely.  I once heard a person speculate that an iodine-based life form was a possibility - no, I would say that it is not, given that iodine can only bond with one single other element and is therefore known as a terminal element.
