Are We Alone in the Universe?

Answer 1

Why hasn't SETI picked up any radio or light waves from any source. You'd think with the high probability of life on other planets per Drake's Equation, that we would've heard something by now.....only silence. It took us less than a century to reach the technological levels to peer into space, why haven't we heard anything......are we alone indeed.

Answer 2

No we are probably not alone, we just have to find them, or where they were. There are many questions to be considered. Here are just a few;-

1. How long does it take a species to develop to the level we have?

Mankind took over 4.5 million years. The Universe is over 12 billion years old. The Planet we live on is over 4 Billion years old. This means there is a possibility that several dozen species could have reached this level, and beyond, and gone out of existence, radio signals could take billions of years to reach us from the other side of the Universe.

2. How many planets in the Universe will, or would, have sustained life for long enough to develop into a "Civilisation"?

Hundreds of thousands, possibly millions, with time it could reach billions. The building blocks of life are everywhere, the chemicals and conditions for life to exist are everywhere. *

3. Will we understand any attempt at communication?

With, "modern", technology we stand a better chance.

(The chances of them having a, "Star Trek", style "warp" drive are very remote. Inter-Gallactic Travel would be next to impossible for any "Civilisation, the distances are just too huge. So any, "flying saucers", or "Aliens", people may claim to have seen would have, if they existed, originated from a planet near a star close to us.)

4. *What will they look like?

Who knows, your guess is as good as mine. There are several different chemicals that in theory would make a perfectly good base for a life-form. Gravity and Environment will determine form and mass.

Answer 3

100 billion stars in a galaxy, and trillions upon trillions of galaxies in the universe? how could anyone think we are all that's here.

god or no god that seems like a terrible waist Of space if the earth is the only life supporting planet in the universe.

I personally be live life will be much more rampant in the universe than we have yet imagined. Why wouldn't there be.

I know Christians wont want to hear this but if a god created everything why would he have created so much stuff that we "his people" could never experience it?

Answer 4

are we alone in the universe?? to answer this question in would be depending greatly on who you are.

for a "prayer", they would believe that god only has made we human and all the species in this earth because it only written about life created in earth in the bible. not in mars or Pluto

for a sciences lovers, they would says that there is another life form in the outer space. maybe they want to feel the excitement of science again and again. they just can't get enough of sciences.

that is if you are talking about aliens.

for me, we are never alone as we ourself can't live on our own. maybe the universe is like that too. will you actually believe that in this big universe, only the earth have life form???

Answer 5

I really don't think so. To me its's the same as Adam and Eve.

The creation story only talks of Adam and Eve and their children, but it is clear that HE created others at or around the same time cause, when Cain was driven away from the family he went to the land of Nod and found other people there. He was so terrified that some one would kill him that GOD placed a mark on his head to keep him safe. He found a wife and went on to start his own family.

All these events let me know that GOD did not stop with Adam and Eve, so who's to say he stopped creating other beings else where.

Answer 6

I just CAN'T believe that we are. To say that we are alone is to deny the infinity of the Universe. Our OWN existence should be all the evidence we need that alien life must exist somewhere in the cosmos.

Answer 7

Ooooohhh, no...my mom saw a UFO once and I have some sites that can prove it.

Answer 8

I say to deny our loneliess is againt God and that is the sin I can not tolerate most.

Answer 9

Guess we'll know when Star Trek becomes a reality, eh?

Answer 10

Probably not but we will never know. Any potential worlds out there are too far away for us to travel there or aliens to travel here.
