Occam's razor really isn't a stringent inference, especially in situations like these where 'simplicity' is an very ill-defined term. An infinite universe could equally be said to be a lot more complex than a finite one. Not that I'm saying I believe the universe is finite; but you can't really form any kind of conclusion at all about it. In the second case a similar argument would argue that there are many other Jim Careys throughout the universe; it's a simpler assumption than the idea that he could just happen once by mistake. |

We do have observable proof of aliens visiting. |
|
That is not a general principle. Life arises in special circumstances. |
|
Basic understanding of emergence suggests otherwise but you know what? Go ahead and be right. It's all you want, isn't it? |
|
Everything works out in the end, sometimes even badly.
Ok, I'll make a serious post in here. All the talk has been about physical beings from other planets in the known universe so far - but Omnis specified physical or otherwise on the OP. |
|
Or you could just throw a huff because somebody disagreed with you again, sure. |
|
Xei, I have one problem with your arguments. And you had a similar thing in another thread. |
|
Life emerges in special circumstances, how rare are these circumstances? I suppose it could be 1 in how ever many planets there are in the observable universe, but I see no reason to think that conservatively, our galaxy alone could be teaming with life. |
|
As far as life emerging under special circumstances, I heard of an interesting experiment. |
|
Spontaneous generation is a myth |
|
Ya it would sort of take the fun out of propagating life, eh? |
|
That is almost definitely junk science; the guy has just redetected the contaminants. DNA is a very complex molecule, and requires elements not even present in just water and sand. |
|
I don't think we should assume contaminants just because traditionally DNA needs more elements from which to form. Perhaps DNA will form with whatever elements are available. Though, again, no DNA on mars. |
|
I don't understand what you're saying. Of course I know that dolphins are mammals..? This is called convergent evolution; 100 million years ago there were aquatic reptiles called ichthyosaurs which looked very similar to dolphins, too. |
|
Maybe they have, maybe not. It depends on how we look at it really. We are all hoping to either catch them on our satellites (if you're interested in this topic, google SETI's Alien Telescope Array) or for them to descend in their great big spacecrafts. In my opinion, if they were really as intelligent as we sometimes think they are (thank you Hollywood), then they would make contact in a more intricate and subtle way. |
|
Yeah I'd imagine they'd make contact at a distance before startling us. |
