First off, let's be clear, this is not a religious topic. Only reason I am asking this, I can't get Evolution Theory, even though It's not like I completely disagree with it.<p>1. We are perhaps the only intelligence species that exists or have existed on earth.<p>Does our Intelligence had any part in the formation of our physical body. Let me ask you in layman terms, If our body was like Elephants, Could we have made as much progress as we did today. The physical body we have, totally support our intelligence, is it mere coincidence?<p>2. It's little weird, that every sci-fi movie (avatar) features ET life according to the atmosphere of their planets. Why it isn't in reality true so far. Again in layman terms, Who said 'O2 and H2O2' are the standard for life.<p>If life had to begin at its own, like it did on earth, why could'nt life2 or life3 begin on other planets according to their own atmospheres, as depicted in Avatar Movie.
Your phrasing and writing style are a little erratic, so perhaps that's why you're not getting a good response elsewhere. You might do more editing before you post if you'd like to get taken more seriously. But I think the questions are reasonable ones.<p>Neither of your questions can be fully answered. Until we've seen a bunch of kinds of life, it will be hard to generalize. It's like trying to theorize about languages in general if you've only ever heard one. It's a lot easier to think about if you have a bunch of examples.<p>Regarding the first bit, I understand that's a topic of quite a bit of disagreement. Early AI pursued a brain-in-a-jar approach, implying that physicality was irrelevant. Others differ. If you dig up the great documentary "Fast, Cheap, and Out of Control" you can see robot scientist Rodney Brooks talking about how intelligence and embodiment are very much related. (Since he went on to found iRobot, he's clearly no slouch.) I haven't kept up, but I'm sure there's a lot of interesting work that's still being done in this area.<p>Regarding the different bases for life, again, we can't say. There's been a lot of speculation of other ways life could be, but we've only got one kind to look at so far, and it's pretty hard to just go and check out a few thousand other planets to see what has cropped up.
"We are perhaps the only intelligence species that exists or have existed on earth." Citation needed. Tool use, language, and many other "human" features have been observed in nature. What is definitely true is that humans are the only species that we are able to reliably communicate with.
Note that while snakes and elephants are physically incapable of using tools, doing so doesn't necessarily require hands (see <a href="https://www.youtube.com/watch?v=hlh0cS2tf24" rel="nofollow">https://www.youtube.com/watch?v=hlh0cS2tf24</a>).
I don't know why I'm responding, this topic is pretty clearly dead, but here's another thing for you to consider. Your point 1 mentions how "the physical body we have, totally support our intelligence, is it mere coincidence" [sic]. We adapt to the bodies we have; other animals adapt to the bodies they have.<p>Albatrosses use a technique called dynamic soaring and can fly across literally the entire ocean without flapping. They've pretty clearly adapted to their bodies; do you feel the development of that technique doesn't indicate intelligence?
