to make u wander and imagin how god is powerful

Answer 2

Who says that there is hardly any life? There may be millions of worlds out there, teeming with life, includeing some intelligent life.

We just haven't visited many of them. We have landed men on only one. We have landed vehicles on only two or three others and crashed rockets on a couple more. And ALL of these were in our tiny solar system. And, only on Mars were we evenexpecting the remote possibility of life. In our system, conditions are too harsh anywhere but on Earth, for the kinds of life we know.

We have yet to even REACH the worlds outside the system. Even our most powereful telescopes can barely make out a few dim hints of possible planets, out there. We have not been able to get any clear pictures close enough to see if any life exists on those worlds.

We can't say "hardly any" yet, because we still don't know.

And will someone tell "asmul8ed" that we have, indeed been "as far as the moon."? Neal Armstrong, July, 1969. And about a half dozen other trips after that.

Oh! How the school system has failed!

Answer 3

We know much about the planets in our own solar system, and several of them have conditions that may have at one point supported life, or may do so now, or sometime in the future when the sun ages and expands. A prime example is Jupiter's moon, Europa - it has a water ice crust that shows signs of cryo tectonics that indicate a warm core. We know that life can exist in the deep cold waters on earth, and beside deep sea vents where organisms exist in temperatures in excess of 200 C., so perhaps there is life on this large moon. Titan is another example - it is a methane planet; and methane is produced by two things only - volcanic activity and biological activity. The temperatures are extremely low, Hoygens revealed methane cut river systems from the methane rain on the methane ice continents.
From the evidence in our own back yard, we can extrapolate that in the vastness of the universe there must be other solar systems. We have seen evidence of planets in other galaxies by the interference their orbits cause on the light from their stars, but we have not seen these other planets. They are millions of light years away. It is probable that elsewhere similar systems have evolved producing conditions favourable to life.

Answer 4

We don't even have the technology to clearly see all the planets in our own Solar System let alone the entire Universe which is infinite. You could say that there is no life on any other planet in our Solar System with reasonable certainty but beyond this system it's impossible to know for sure one way or another. Personally, I can't believe that with the vastness of the Universe that there is no other life out there other than us.

Answer 5

Is man as a species really so arrogant that he believes the universe was built for him alone? Out of the billions of planets that exist in the Milky Way several will have life, but fewer will have intelligent life. Those with intelligent life technology will be at different levels for all of them, hence difficulties in communicating.
Stars are being born, and stars are dying, they are of different ages, so too will be their attendant planets, and any life forms upon them.
One day that unmistakeable signal will come, and we will know we are not alone, but what manner of creature originated the signal, we most probably shall never find out.

Answer 6

first of all we dont know if there is life on these planets. It's only speculation because these planets appear to not share the same properties that earth does, which is stupid of us to think that an earth like planet it the nly place in the universe that life can exist. Heck no one really knows if there is life on the moon and we have walked on the moon. But we didnt explore everywhere on the moon.

Answer 7

Statistics. Life has to have some very certain, specific things in place to happen. Also, we have not discovered all of the planets, have not been to all of the planets, do not have good enough technology to review all of the planets, and have never seen any form of life other than our own, so would be prone to miss something that was totally ALIEN to us, so to speak. "It's Life, Jim, but not as we know it."

Answer 8

We have visited only the moon right? And only probed a couple of planets in our own solar system. How did you decide that there is no life on the millions of others we haven't explored? What about all those we don't even know about?

Answer 9

OK?? is this a serious question?? How does science know anything about life on any other planets. To my knowledge we haven't ever been even as far as the Moon humanly, as for robots and whatnot, only as far as Mars, oh yeah and a few probes which took really fa range pictures (none of which are on any planet outside of the solar system). Besides all that what we classify as living organisms on Earth, is only based on what we know about here on Earth. Any environment could be conducive of life based on the ability for that specific life form to subside in that particular environment. There could be asteroids in our own solar system with a life form which only needs carbon to live on. Planetary science is in such an infancy that it would be impossible to determine at any certainty life outside of Earth.

Answer 10

It can not be said that there is hardly any life on other planets because a man is altogather helpless to exactly say even 1% about other planets,as universe is so laaaarge.

Answer 11

If only 10% of all planets support life and only 10% of those support intelligent life and only 10% of those support life that can reach out into the stars, how long di you thinkit will be before we are contacted in a positive manner.?

Haven't you noticed that technology seems to develop as we mature enough to use it wisely?
