i'll be over with my chainsaw in a minute.

Answer 3

There are so many stars and galaxies in the universe that the odds are extremely great that there are other planets which do harbor life! The odds are very much against it being otherwise. Now, wether we are the only humans that exist in the universe is another thing. I would say that most of these planets could contain Dinasaur like creatures or mammals kinda like the earth used to be. Or, who knows mabe there are human-like beings out there! We may never know.

Answer 4

The term universe has a variety of meanings, based on the context in which it is used. In strictly physical terms, the total universe is the summation of all matter that exists and the space in which all events occur or could occur. The part of the universe that can be seen or otherwise observed to have occurred is usually called the known universe, observable universe, or visible universe. Because cosmic inflation removes vast parts of the total universe from our observable horizon, most cosmologists accept that it is impossible to observe the whole continuum and may use the expression our universe, referring to only that which is knowable by human beings in particular. In cosmological terms, the universe is thought to be a finite or infinite space-time continuum in which all matter and energy exist. Some scientists hypothesize that the universe may be part of a system of many other universes, known as the multiverse.

Answer 5

Well, there's us, for one. Probably a lot more - even if the chance is a billion to one, there are 200 billion stars in our galaxy alone, and probably millions of galaxies. When we start exploring our solar system more - Europa and the moons of Saturn - we might have a better idea as to whether life is easy to find or not.

We haven't found any planets other than our own that are similar to ours (enough for life like us to exist), but that's only because our current technology for finding planets can only find planets several times the size of Jupiter.

Answer 6

So far our planet is the only inhabitable planet. There is no proof of there being any other life in the universe. Not that I believe we are the only living things, there is just no proof stating otherwise. I do believe there are aliens and other life forms, we just haven't found them yet becasue they are too far away and out technology isn't advanced enough to detect them.

Answer 7

Right Now I know of One Planet For Sure, That is Earth

I am not sure if you consider the moon a planet, but life has been there before with Neil Armstrong's one small step for man, one giant leap for man kind

I am not sure if you consider robotics to be life, Although there are robotic devices on mars taking photographs and collecting samples.

So I guess there is life on 3 planets

Answer 8

If we define life as we know it, about 1000 planets (using the Drake Equation)

Answer 9

6723^43 number of planets excluding earth

so the total is 6723^43 + 1

Answer 10

Of all the grains of sand in the average childs sandbox.....how many have a green speck in it? Does that clear things up? We can't be the only ones.

Answer 11

according to the drakes equation..quite a ton o them..search around for that equation :)
proved: 1 (earth that is )
