do you think there is other life forms them humans? Are we alone in the universe?

Answer 1

i consider any molecule that can replicate itself living. if there is any chemical process anywhere in the universe that involves a molecule making copies of itself by any means, that is life. Of course there may be a spiritual race of beings as well which have sentience but no physical form.

screw that whole theory about there being billions of planets in the universe so one of them may be able to support life as we know it. that is pseudoscience. in the typical spiral galaxy there is a narrow range at which life as we know it can develop. if you are too close to the galactic core, the radiation from the densely packed stars will kill everything. if you are too far out from the core, you lack the necessary amounts of carbon to form life as we know it. now shrink down to the solar system level. there is another narrow range at which life as we know it can develop. it must be in the right range to the star to allow water to be in a liquid state at least some of the time. the planet must have a molten iron core to develop a magnetic field which will shield any developing organisms from harmful radiation. the odds don't look so good now that theyve been explained.

Answer 2

Looking at the numbers theory, there are billions of planets in the universe so it's unlikely that Earth's the only one which can support life.

Furthermore, I really do hope that there are more intelligent life forms out there because if humans are the most intelligent life forms in the universe than god help us all.

Answer 3

I do think that there is other life forms. How could we possibly believe that we are the only ones out there? In fact there is evidence that Mars could once have supported substantial life. And now there is microorganisms living on mars, so even if it is the littlest life, i don't think we are alone in this universe.

Answer 4

There are billions of stars in this galaxy alone. There are billions of galaxies in this universe. Think of all the planets that rotate around these stars. Is it reasonable to say we are alone when there are so many other possible sources of life? Are we so arrogant to think we can be the only intelligent out there? It is not impossible but not probable that we are alone.

Answer 5

there r life forms other than humans that r livin in some other planet.i think that u might have learnt bout the UFOs-unidentified flyin objects.i also agree with u that many reports on objects may b created by imagination or it might have even been a bluff by some1.but even if there r 20 reports in this world,at least 1 of 'em must b correct.there r presently 2 lakh reports on UFOs and at least 1 person out of the 2 lakh must have been speakin the truth.

Answer 6

Like people said above, Drake's Equation states a high probability. The "WOW" signal captured by SETI in 1977 has been the only ET signal ever recorded. That short 72-second signal is all we have. You'd think of all the millions of possibilities we'd hear more. So what does that mean?

1. we're alone
2. others are not advanced enough to send signals
3. others have evolved differently
4. others have advanced further than us and choose not to signal us, treating us like ants in an ant farm

Myself, i cant wait till "first contact"

Answer 7

Of course we are not the only ones in the universe, and I think it's very arrogant when someone says they think we are.

Answer 8

I think it takes a pretty narrow minded, egotistical person to think that we are it. As Jody Foster said in the movie Contact. " It would be a terrible waste of space " .

Answer 9

Alone? Absolutely not!

Answer 10

Statistically, no we are not along. Although statisitcally, the distance would probably be far too great between us and them to prove it.
