Do you believe in life on other planets?

Answer 1

oh definitely.... it's kind of egotistical to think we are the only ones out here... and just in case I have my aluminum hat ready so they can't read my thoughts...lol..

Answer 2

My answer to this question depends upon our collective definition for the word "life". Are we assuming life on another planet would have to be a carbon-based organism? What would be the criteria?

How are we, as humans, certain that we know all forms of life that could possibly exist? According to science, there are many species on this planet that have recently been discovered and previously unknown.

Dr. Frank Drake has created a formula which takes many of these questions into consideration, and using it, predicts the number of planets within our galaxy which could sustain life:

N = R* fp ne f l fi fc L

N= planets with life, which is equal to:

R* is rate of formation of suitable stars (stars like the Sun) in the Milky Way galaxy
fp is the fraction of those stars that have planets
ne is the number of planets capable of sustaining life around each of those stars having planets
fl is the fraction of planets capable of sustaining life that actually evolve life
fi is the fraction of those planets where live has evolved that evolve intelligent life
fc is the fraction of planets with intelligent life that develop the capability to communicate
L is the fraction of the planet's life during which the intelligent life can communicate

Depending upon the data you use for this formula, you arrive at an estimate anywhere from 20 planets- 500,000.

The challenge here, however, is that outside of our solar system, the nearest planets are 10 light years away, or the distance light would travel in 10 years.

Considering that light travels at a rate of 186,00 miles per hour, it is not difficult to realize that 10 light years is a long distance to travel for anyone- and so the chances of meeting life from other planets, barring any huge advances in space travel, remains remote.

Answer 3

Yes. If there is life on 1 planet (earth), there must be life on others out of the infinite number of planets in the universe.

Answer 4

I do believe that there is life on other planets. Maybe not in our solar system, and maybe not even in our galaxy. But there are so many planets in the universe, that the chances are very good, almost a certainty, that there is some kind of life on some planet somewhere else.

Is it just bacteria? Or maybe just some fish? Maybe just a lizard? Or inteligent humanoids building spaceships (like us)? Who knows?

Answer 5

What does 'belief' have to do with a scientific question? anyway, i think there's a high probability that life exists on other planets just based on the number of other solar systems in the Universe.

Answer 6

statistically it is very likely that some kind of life exists on other planets. The questions are: Since we are limited as to where we can go to look, will it be where we can find it? and Will we recognize it if we see it?

Answer 7

The way I see it, is that if God made us, he can make thousands of planets and civilizations just like ours. But maybe a bit less corrupt. It seems awfully conceited to think that we're the only ones. And it wouldn't be in the Bible because the Bible is for Earth and humans, and God wouldn't put it in the Bible unless he thought we needed to know it.

Answer 8

You'd have to be pretty naive to think that God made an endless universe but only put life on one planet.

Answer 9

Amount and type of conciousness is more important. There are many types of lives, Virus like organism are present definetly in many planets.

Answer 10

Yes. The Universe is very large.

Answer 11

Space is big. We are talking trillions of stars. As unlikely as it is that life gets formed, it is hard to imagine in the massive universe there is no other life.
