Dinosaur Type Creatures Existing On Another Planet

Question

ok my question, why do people think that if we ever discover life on another planet it would be either 1) small worm type creatures or 2) little green men (something that closely resemble us)?

yet rather than little green men or worms (out of our solar system) wouldn't there be a good chance ET would be dinosaur/mega-beast type creatures? afterall they are the type of animals thats ruled our planet the longest, we humans are hardly a dot in earths history tbh.

Answer 1

An excellent point, but the answer is no. Dinosaurs existed for as long as conditions were favourable for their existence. Just because on Earth such conditions lasted for a very long time does not mean they are likely to exist somewhere else. A little green men are as good a guess as giant reptiles.  

Answer 2

Life is the product of it's environment.  Life first gets a foothold by brute strength;  later, it maintains itself through clever tactics, and still later, through mental prowess.  

So, all things being equal, life on an identical Earth, but one that was a little closer to it's sun, or maybe had a longer day, etc - whatever factors exist there - will dictate what shape and size (and features) a creature on that planet will obtain.  

Answer 3

interesting i used to question about this too .. but i believe we would be originally some small worm type and living around in many galaxy as well as i believe in the rule of recarnation " the next and past life "

hehe its too complicate to understand but who knows may be in another galaxy there still dinosaurs exists.

Answer 4

I think it comes down to a limitation of our imagination.  If we do find sophisticated life on another planet, it will almost certainly be unlike anything we've seen on Earth.  Life can evolve in practically unlimited ways, and ours took a given path; life elsewhere would almost for sure have worked out different solutions with different shapes and so on.

Answer 5

Statistically you would find more bacteria than anything else.  Its only been about a billion years since Earth had advanced life.  Before then it was bacteria for about 3 BY.  Probably most worlds never develop advanced cells and go on to develop animal life.   On earth that seemed to require two major snowball earth events, each almost 100% fatal.  If animal life does take hold, it seems likely that it would develop into a dinosaur stage: large animals with big teeth.  Earth would still be in that stage if it weren't for a big space rock crashing into the Yucatan Peninsula 65 million years ago.  

Answer 6

It's entirely possible dinosaur type animals may exist on other planets. There is much we don't know about the origins of life and the conditions that life can sustain itself in. We do know there have been several mass extinction events on Earth, which have given rise to several epochs of life on this planet. In the entire 4.5 billion years of our planet only one species has developed intelligence and the ability to successfully control it's environment. Clearly, just because life exists, that doesn't mean it will develop  intelligence. After all, if you can run fast, have a great sense of smell and sharp teeth, what need you you have to develop intelligence? It's conceivable that without mass extinction events that have occurred on Earth, intelligence may not have developed at all.

Answer 7

On the one hand, single celled bacteria ruled the Earth far longer.  It's quite possible that dinosaurs would have produced our little green men if the asteroid hadn't struck. There was a species whose brain was growing quickly just before hand.  Most dinosaurs had pea brains, but one had developed to the size of a human baby's.  A set back, to be sure.

But if you look at Earth's entire history (including the future), you should see billions of years with intelligence too.  And the big bad dinosaurs' day isn't the long rule it seems now. I don't expect that Earth will be without intelligence again.

Answer 8

I say worm thingy... isn't that how we all started out, little squiggly lines. lol then the dinosaur or lizard type creature.  I hope there are dinosaur type creatures out there, I want to see one =]

Answer 9

The fact that dinosaurs may have enjoyed the longest stay on earth does not mean that there is a better chance we would find such creatures on other planets. The dinosaurs and reptiles in general, proliferated the earth in their heyday for many reasons. Evolutionary and extinction events played the biggest parts in their development. In addition, the size of land masses played a big part.

All of the above factors may never have been replicated on any other planet for such creatures to evolve. So, you probably have a better chance finding small worm type creatures on other planets.  

Answer 10

could be - all the above

Answer 11

They are grasping at straws about something they virtually know nothing about. I mean we all know that all aliens are actually Killer Klowns from Outer Space that want to come to our planet and shoot us with popcorn guns, throw acid pies at us and trap us in cotton candy cocoons so they can drink our blood.  

Answer 12

there is no guarantee that we would even recognize the lifeform as alive, or even as having a familiar shape, they could look like clouds, they could float in the sky like balloons, they could look like plants yet behave like anymals... so the posibilities are endless and if u statistically tried to get the chance we found dinosaurs on space u would get a number you could not write in 1 day
