Does Alien Life Exist?

Debate Information

For me, it's almost certain there is other life it's just a matter of finding it.

    Yes, it is very likely that there is other life. There are many other galaxies and planets, some of those might be able to shelter life.

    I personally think the universe is definitely big enough for some form of life on a planet not on Earth. But lots of criteria must be met for life to be possible (right distance from a 'sun', presence of water, a way for life to get food/energy, atmosphere to protect from space's void and harmful radiation, and maybe a few more), so I'm also a bit skeptical if life would exist not here.

    So, short answer, I don't know for certain. I might look up if someone did find a suitable planet. And if someone did find life, it would probably be a simple life form, like bacteria.

    Unless you have evidence (beyond probability), you can not state that aliens do exist. (Liklihood is not equivalent to fact.)

    Yes, alien life is highly probilble according to many scientists possibly. Out of all the planets, some may be habitable to life.

    PowerPikachu21 Life can exist in many many unexpected ways. Also a current scientific underestimate says the universe is so big that their is a decent chains of it. Based on science. But until you find it you can never say for sure. If life must be made by cells like some sources tell me those odds go down.

    The short answer is, we do not know.

    The long answer is, we do not know. No, seriously, our knowledge of how abiogenesis works, of what types of it can happen, of what environmental restrictions can be posed on it (if any), what elements must be involved in it and so on - is extremely poor at the moment. Maybe life can only exist within a very narrow range of parameters, all of which are very close to our Earth's environment. Or maybe it can exist everywhere, from cold space to cores of the hottest stars. Some life forms we might not even be able to recognize as life forms, should we encounter them, as they will not resemble anything our intuition says about what a living being must look like.

    I would expect there to be a very large diversity of life forms inhabiting a large variety of environments - but that is an intuitive guess, and not something that can be logically justified. It would be strange if in the observable universe with hundreds billions of galaxies, each harboring hundreds billions star systems, each potentially harboring multiple planets and planet satellites, with an unimaginable number of smaller objects such as asteroids or comets - life was confined only to one or a few planets. At the same time, the Universe tends to surprise us as we learn more and more about it, so I would not draw any conclusions just yet.

  • Ya. There probably is alien life.

    Some physicists believe it is mathematically impossible for their not to be alien life elsewhere. Some even believe that mathematically, it must be true that other earths with human beings just like us, or even exactly like us exist. They theorize that there could be millions of people exactly like you, who live on planets exactly like earth. The universe is so much larger than humans can visually conceive of. If galaxies contain hundreds of billions of stars, and most of those stars have planets that orbit them, and there are 2 trillion galaxies in the "observable universe (that means there's probably many more that we can't see) there must be copies of us somewhere. But then again, that's just a guess!

    On one hand, the universe is huge. On the other hand, life forms only in specific conditions. I don't know which side weighs down as I am not a scientist. From what I read though (which might be wrong), it is somewhat likely for alien life to exist but not as green head UFO guys, just as bacteria. Still though, we should not assume things. We just don't know, let's leave it at that.

    If you Globe-earthers believe in planets like these:

    Then for the life of me I don't understand why you would question the existence of aliens like these?

    In the context of the O.P. of course aliens exist, .. what a question?

    Sci-fi movie going on the moon, right after man lands on the moon.
    Sci-fi movie of man on a planet called Mars, .. man sends a Rover on Mars, and is planning to send man on mars, .. it takes eggs to make scrambled eggs. It takes planets to have aliens, .. what's the big deal?
    It's almost like asking: "Can Peter Pan fly?" Well duh, .. everyone knows Peter Pan can fly, .. all he needs is faith and a little Pixy dust.

    My question is, why is this post in the "science Forum"??

    The odds are too high for there not to be alien life on another planet in another solar system somewhere assuming that are universe is endless. Even not assuming it is endless throughout the visible universe the number of galaxies is just too high.

    First you'll have to find evidence for this so called: "Universe with a solar system with planets named after pagan gods, ruled by; Helios",
