I definitely believe in extraterrestrials. I have my own personal reasons for this, but even if I didn't, not only is it extremely probable other planets have life, it's also rather evident we have been visited on this planet.

That visit Earth? No. In the whole universe? Sure.

I think it's very possible that ET's have visited us, but I'm not entirely convinced by that explanation, as some UFO sightings are a little too bizarre and nonsensical to be chalked up to aliens from another planet visiting earth. I believe something is probably visiting us, but whether that is aliens or something much weirder, I really don't know. Jacques Vallee, a scientist who has studied UFO's, thinks most UFO sightings are too weird to be explained by the ET hypothesis, and I think he's on to something.

I have seen actual unidentified flying/floating objects. One of them was kind of strange. I'm not against the idea very heavily.

it seems shakespeare had one of his characters say something along the lines of "the lady doth protest too much, me thinks"- our own mrs. government is a lady which has protested for decades now, insisting that there is nothing out there but space and the occasional astronomical object. but i am one of legions of crazy but not that crazy people who have with their own eyes seen something out of the ordinary in the sky, such as a shiny silent orb which moved away at great speed when pursued by jet fighters scrambled out of mcchord AFB one summer day 3 years ago. it was no mylar party balloon, at least none of the variety which could outperform a jet fighter plane :roll:
people smarter than me [such as the late j. allen hynek] do not discount the possibility of ETs visiting us from god knows where. former state governers jimmy carter and fife symington have publically claimed to have seen something up there as well. artists from the middle ages also have painted what look like UFOs with observers, in the backgrounds of a few paintings. there seems to have been something afoot in human affairs and UFOs for much of recorded human history. i believe that much more is known about this subject than the general public is privy to. but pay no attention to me, i'm just the crazy aunt in the basement that nobody wants to think about.

I would hesitate to call them "extra" anything if they don't leave their own territory, and I doubt that they do. I have no real clue on how often on a universal average living systems initiate.

I think it is possible for life to exist on planets other than Earth. I am a Christian though, and my views about aliens are basically derived from C.S. Lewis' Space Trilogy starting with Out Of The Silent Planet. If they do exist, and God is the designer of both them and us, then there should be common design features. Often taken for granted in science fiction, DNA is not chemically deterministic and neither are the patterns of the genetic code, so if abiogenesis were to be the source of life, such alien life would almost certainly not have the same kind of heredity molecule. Then ensues the ad hoc addition of panspermia if such life were to have the exact same molecule of heredity, deoxyribonucleic acid, whereby evos would rather evoke passage through space of the DNA molecules from one mega distant location to another just so as to reject the mere possibility of a common designer.

Terrestrial refers to the Latin name of this planet, Terra. Extra just refers to the nature of such creatures as not being from the planet Terra.

Wait a sec... I think i'm on to something here, but i may be confused... so Ex-Terra.... And Terrestrial... Hrmph... o.O Isn't this a case of redundancy? Or... It's either like... From outside Earth.... or not being "terrestrial" as in touching the ground. <.<

Hrmmmmmm. ><

Anyways... Let's just say that i'll leave the possibility that alien life-form exists on the table. But i guess we'll never know unless they visit us, seeing as we "could" have ran into contact with them earlier were they within our current reach. <.<

Terra is a noun form and terrestrial is an adjectival form, in English. Ex, in Latin, means "out of". But extra, in Latin, means "outside of". The antonym of extra is "intra", which in Latin means "inside". However, the word "intra-terrestrial" has not been coined, although there are word sets which display this opposition of meaning, such as introvert and extrovert. Related words are "endo" and "exo", which are from Greek rather than Latin, of which examples of usage are endothermic/exothermic, endoskeleton/exoskeleton.

BTW, ex-Terra would have the meaning of something which has left Earth, an item or creature which has gone out from Earth.

Yes but.... With the small exemple i made, i was trying to point out that they both have the same "root", being (ex-)terra(-strial).

That's correct then, they certainly do.

Interesting you said that, because from what I've heard, most of the ETs reported are very humanoid and similar to us. Whether they shape shift to appear that way, or actually are designed the same, or are related to us, I don't know.

I have always hated how some scientists get all excited that "maybe life started on mars and came here on asteroids". Well, sure, maybe. But they get a little excited about it, positing theories when its just as likely, if not more, that it all started here. They are just looking for a creation myth, ignoring probability.

Note that I dont have a problem with the idea of amino acids arriving from space(I'm sure it happens). I dont even have a problem with life starting elsewhere. Its just that they get so damned excited about it, and discount that the basics of life are here.

That being said, you have a point that there could be all sorts of life forms out there that we fail to recognize for the very reason that they are of a different basis from us.

Yes. I don't believe they've ever visited this planet, though.

I would bet that some other life exists. It might be intelligent. I doubt we've ever been visited though.
