Is there life on other planets?

Answer 1

I love all the definative answers here. Everyone is pretty convinced of their opinions.
There seem to be two broad groups when talking about these things.
The ones who are convinced that there is life simply because of the volume of planets.
There are others who believe we are alone because it conflicts will religious doctorine.

I don't go either way, but to hedge my bets and assuming if there is life it is hostile, I keep a lead pipe under my bed.

Answer 2

No. We have had discovered hundreds of planets and never found a trace of life. Latest studies on mars suggest that because its biochemical composition in the future life may arise just as it did on earth. Life is an extremely complex subject that comprises many factors in order to develop. The sun has to be the right size, the planet located in the right orbit and must have a satelite, its core needs to be at a temperature in which combined with the star (sun) is able to sustain life... and so on.

People speculate a lot and say "the universe is very large and we are not alone" Since galaxies share common elements such as hydrogen, helium, silicon, oxygen, and nitrogen, the laters to a lesser extent, its common sense to infer theres life in some point in the universe, but how far? How many galaxies have we observed and not seen a planet like ours? For the record none. It may exist, but we dont know yet.

Answer 3

I really think that there is a life on other planets, but only in planets that have the common characteristics like our planet Earth.. It must have an atmosphere and can support life, like Hydrogen and oxygen. There is/are planets out there millions or billions of light year away i believe,, and creatures there is not nearly close to creatures in our planet,, because gravity, air density, water density will never be like ours here in that planet , that affects he evolution of things,, Thank you hope this can help.

Answer 4

Considering the universe is nearly infinite in its size, the chances are good that there is life of some form on other planets.

Answer 5

Why would we humans even think there cannot be life on other planets or galaxies. Why would we think we are the only viable lifeform that exists.
We may never find out that answer.

I hope there is and it is a friendly lifeform.

Answer 6

There could be. The universe is so big to just have life on one freakin planet.

Answer 7

Well, to paraphrase some British comedian, "I sure hope there's intelligent life somewhere out there in space...'cause there isn't f***-all down here!"
I'm convinced there's life on other planets in other solar systems; we just haven't found it yet, but we probably will when (if?) we become a spacefaring race.

Answer 8

With trillions of stars out there, most with planets revolving around them?

I say yes.

Answer 9

Apparently, some people call them Democrats while others refer to them as Republicans!

Answer 10

No man knows exactly what is life, so no one can tell yes or no.
If you mean human beings, the answer is no.
