Is there life on other planets?

Dear Hari:
You asked a good question.
Let me check on that for you.
I will need to look through about 100 Billion
stars in the Milky Way Galaxy to see if any
of them have planets, and if any of those
planets have the necessary ingredients for
life on them, you know like water and a good
dense atmosphere filled with oxygen and nitrogen
and carbon dioxide. I am rather limited at this
time and will not be able to do the equivalent job
seraching through the 100,000 plus other galaxies
beyond the Milky Way, and I do appologize for that
shortcoming. This search will probably take me
a little longer than the next 1800 years to accomplish.
However, I promise to shoot a note out there to you
if I find anything interesting.

Our own galaxy is about 70000 - 100000 thousand light years across. The universe contains billions of galaxies, it is highly unlikely that Earth is the only planet that has life.
The Drake Equation: N = N* x fp x ne x fl x fi x fc x fL
N, the number of communicating civilizations in the galaxy.
N* represents the number of stars in the Milky Way Galaxy
fp is the fraction of stars that have planets around them
ne is the number of planets per star that are capable of sustaining life
fl is the fraction of planets in ne where life evolves
fi is the fraction of fl where intelligent life evolves
fc is the fraction of fi that communicate
fL is fraction of the planet's life during which the communicating civilizations live
Try the calculator and see for yourself!

Of course there is, but probably not in our solar system. But it would be arrogant in the extreme to believe that there is no life on any other planet in all the other star systems in the entire universe!

of course.. the universe is infinite right? meaning there would be infinite of EVERYTHING, if you can grasp that. infinite amount of planets. personally, I think that life came on earth when it first began on a meteor, like a meteor with bacteria on it. so what if other meteors are bringing life to other planets and they are evolving custom to their planet?

Maybe, you never know if some kind of people might adapt to the conditions that some planets have...

to think otherwise,is arrogant,ignorant,& an insult to your own intelligence, there are many stars out there, with there own planetary systems.
& there are more stars than there are grains of sand on this planet.

Organic life, as in plants, water, bacteria? Yes

some scientist discovered bacterias on mars. maybe we can live on mars if there is water,oxygen,etc.
