if we ever find any microscopic life wht do you think it wold look like?

Did you ever read the Dr. Seuss book called "Horton Hears a Who" ?   about horton the elephant hearing tiny 'people' called 'who's"  that live in a tiny speck of dust? he carried it around  so carefully so the 'whos' wouldn't get hurt....... what if planet earth is just a tiny speck in the great universe? what if micro-organisms have even smaller life forms visible to them? It could conceivably go on into infinity in either direction!

I don't know.  But it would seem to be something not of this Earth.  I'd be interested to find out someday though.

I'm absolutely confident there is life out there.  But I hope they have better things to do than draw designs in crops and play peek-a-boo with airline pilots and nerds.\n\nAnd we only look like we do because of the way life developed on Earth.  There is no reason to believe that aliens would look anything at all like us.  Unless of course we came from the same place at some time thousands of years ago and we adapted to Earths enviroment, then of course we could be somewhat similar.

adding to snagelfritz, there could bve life in a gas giant.  They would float on blimps, and be hunted by gliding organisms with sharp claws to tear right through them.  Several forms of life could exist in the solar system, like also on titan, there could have possibly been life, giving the fact that the atmosphere is made up of the same elements as ours!

I think life is very hardy and pops up even given the worst conditions, consider those worms that live at the very bottom depths of the ocean, where there is no light or heat except coming from the vents, and where scientists assumed to never find life. And if you believe that and believe that we are here by chance, just imagine all the different planet situations out there in the whole universe, its impossible for ours to not be duplicated or even have another system with our conditions.

nope i dont think soo cuz non living factors cannot become living organisms.....but its jus a guess ok=)

In my opinion, things are just way to complex for general evolution. I could see maybe a large colony of mold somehow coming into being on it's own,, but all the complexity we have here., No chance.

If the habitat is there for them, yes i do , it would be very interesting to see how they live, especially when they are being pushed into extinction here on earth.  If similar habitats exist on other planets that they can survive in, at least that way they will not be forced into extinction, the way this planet is going we will soon have no creatures left.

According to current accepted beliefs, there is no people in Mars, although there has been fossils of single celled organism.\n\nWe should stick to this, until we found any further information about living things in Mars.

Supposedly, we can only see just a small fraction of our universe.  With some many places, the odds are pretty good that there exists life somewhere else in the universe.\n\nHowever, with those odds, the chance of us finding them is almost zero.  Humans have existed for almost no time at all compared to the life of the universe, so the chance that another life form exists at this exact moment in time is very small.\n\nWith the large universe, somehow one of us would have to get interstellar travel.  But the chance of one of us randomly bumping into each other is very small because the universe is that large.\n\nAlso, who says other life forms want to expand to other places.  Maybe both of us will just be happy living on one planet and staying there until the life form goes extinct.\n\nThe only way we could prove any of these theories is to actually find other life, but given the above, the chance of that is almost zero.\n\nAll that said, I think there is/was life out there, but I don't think we'll ever find it.  Maybe they made it to Type I and self-destructed like we might. :)

If the fossilized remains of life is found on Mars, it would be a big deal but still leave a lot of unanswered questions.  Did the Martian life evolve separately from that on earth, or did a single form evolve on one planet and transfer to the other?\n\nOn the other hand, if life is one day discovered on say Europa, and that life is found to be fundamentally different than terrestrial life and uses something other than DNA to carry information, that would be huge.  It would show life evolves naturally whenever conditions allow, and would basically say the universe is full of life.  Earth would once again become a little smaller, and we would doubtless get down to some serious speculation about how low we need to keep our heads, as Hawking would say.

Not yet. All life WE know is carbon based. Try to find speculation on silicon based life, for a start.

Its appearance under a microscope.\n\nPersonally, I think Giardia lamblia looks a little like a balloon with eyes and a modest length of string tied on it...

Well, I'll tell you my best guess and then in a million years, let me know if I turn out to be right.  I think we're going to be:\n\nBrown.  If we last another million years, we'll eventually all become the same color -- some shade of brown.  "White" and "Black" will refer only to colors and not races.  Even today, the advent of global communication and travel means that racial distinctions are being blurred.\n\nBigger.  First-world countries have higher average height and weight than their developing counterparts.  I suppose that this is a nutritional issue and not a genetic one.  But if we're still around in another million, it would be safe to assume that we've figured out our food production problems.\n\nPeaceful.  Chances are that we'll kill ourselves off before too long, but if we survive, we've beaten our own worst enemy -- ourselves.  This could go either way; peace might come only after death and destruction limit our ability to make war.\n\nAltered*.  This is the wild card, and it's a big one.  We're already on the cusp of genetic engineering already; sooner or later, we'll be able to basically choose what our offspring look like.  Who knows what will become stylish along the way?

The universe is so huge that it would be a common sense thing to belive that life exists else where. But it would be a question how that animals might have formed?. How will they differ from us? How will they reproduce or reproduce in first place? or will they ever die? will their genetic code read lines of death or aging?

the magical composition for a planet to have life on has extraordinary complexity therefor life as we know it in the millions of planets we know so far about is almost impossible but not impossible . perhaps life does exist but not in the way we would expect or could possibly think of . lets not forget that even when we have been for so long in this planet it continues to amaze us , so translating that to the universe i think is just a matter of time before find what we less expected in the most unusual ways .

Sure there are. There are many as-yet undiscovered species within out own world. Remember also, that we are but one of thousands of "species" living on the earth. While not provable at this point, given the vastness of our universe, it is likely that there are other forms of life elsewhere. I'd not imagine "little green men" as much as simple-cellular forms.
