Are we really alone in this universe?

Answer 1

FAT CHANCE.

considering that, there are approx 200 billion STARS only in our galaxy which means, putting in account 2-3 planets (no more to each star) we have approx half a trillion planets. (in our galaxy).
Therefore, taking in consideration 0.000001 that might be habitable, we still have 500000 planets that they might be habitable. from this number if we go down to .0001 with conditions similar to earth, we have 500 planets that might have life similar to earth.
The astronomers rise this number to 100.000 just for our galaxy, but I doubt if it right. But I doubt that we are alone. It should be very egoistic.
On the other hand...... consider that there are billions of Galaxies.
How should be posible to monopolise the "inteligence" (??????) in whole universe? It should be not only egoistic but arrogant too.

Answer 2

This question has vexed physicists and astronomers for more than a Millenia. There is now a branch of theoretical astronomy devoted to this very idea. The numbers alone are staggering. For our Universe there are over a hundred million galaxies each of which has over a hundred million stars, doing the math makes overwhelming numbers for the argument for the existence of other life more than a possibility. As well as this there is the possibility that other life is not carbon based, it could be silicon based as silicon is the most abundant substance in our universe. I'd like to think we aren't alone here but proving it is a little difficult at present.

Answer 3

You are not alone, but you might as well be. Over the centuries, your planet was a curious place to visit once or twice and was not considered very interesting . Sure, your wars showed us how undeveloped you are as a species. Your infantile,(in cosmic terms) dependence on god concepts does not bode well for you and neither does your penchant to breed beyond your planet's ability to sustain you. We are now showing an interest in you because it is not often that we get to observe a species commit suicide. You are so close to maturing as a sentient species and it will be a shame to see you kill yourselves. There are just not enough of you becoming rational enough to force the issue. You let the least among you determine your fate, so be it.

Answer 4

With the amount of space in the universe it would be hard to believe that we are alone, but more possible that we will just never make contact with anyone else

Answer 5

I cant imagine that we are alone in the universe. When you take into consideration how many galaxies there, how many stars are in those galaxies, how many stars have planets and how many of those planets could potentially sustain life, I'm sure there must be countless of planets with life on them.

Answer 6

The odds are pretty good that some other kind of life is out there.

But it easily could be a very primitive life form that is nowhere as advanced as us. But vice-versa is just as possible.

Sometimes I wonder if more advanced humans came from space to earth about 10,000 years ago, and supplanted the prehistoric-man that was existing here at the time.

Answer 7

I highly doubt that we are the only intelligent life in the universe. Hell, we aren't even all that intelligent as we claim to be! There're billions upon billions of planets in the universe and the chances of another earth-like planet are very good.

Answer 8

We are one among many.
There is no proof at this time but there is little doubt that technological life proliferates throughout the universe!

Answer 9

no we are not alone the universe is very large in our solar system it is possible but there are so many solar system so we can expect life on other planet which belong to other system even scientist agrees this

Answer 10

No we are no alone in the Universe.
The Christmas story is about an Angel (non human) visiting a girl (Mary) and telling her she was to give birth to the son of God ( Jesus ).
