Do you believe there is life other than on Earth?

Well, it is one of two things.
#1. Earth is the only planet with life.
#2. Life developed on other planets.

To this day, we haven't found how life evolved from ooze to living matter. But the parts, which are use to build life, are abundant.

I see. I didn't know Capone, Mussolini, or Nixon were big on theories. I thought Capone was just a gangster, Mussolini a dictator and Nixon just a little sneaky.

We don't care about other life forms. We are only interested in life as we know it. Everything else is not worrying about. We have plenty of other life forms on our own planet.

There may be mosses and microbes but who cares?

However. Our closest contacts. The moon. Nothing. Not even a mosquito. Mars. Nothing just an uninhabitable desert.

If life was so common we should be able to find it in our own planetary system. But it's not that common as some would have us believe.

They find water elsewhere and it's not H20. I have followed this topic since I was about 12 years of age.

Scientists at one time believed we were the only life forms. Then they changed. Now they are com ing back to the theory that everything out there we are finding is just too hostile for our life type. Even an extreme orbit of a planet around a sun eliminates that planet because of too much extreme.

But in all this and all the money being spent and the research. They are not looking for mushrooms. They are looking for intelligent beings who can communicate with us. Why then all those monster antennas and searching for signals? Able to reproduce itself is Life.? Bacteria can reproduce itself and so can a virus.

Very naive. Life does not have to Be just like us, to be interesting or to be worth while looking for.

Those giant antennas are not just looking for intelligent signals. Radio astronomy is a major field of research. Wavelengths that are invisible to our eyes have greatly broadened our knowledge of what's out there. If they should stumble on an intelligent signal or other sign of life it would be great. But, that's not the main reason they are being built and used. One use is to communicate with the various probes and rovers we have scattered about. Imagine how weak the signal must be from the New Horizons probe that just flew past Pluto.

Also, I think you are inferring that bacteria are not alive. I'm not sure why. IF it weren't for their growth, we wouldn't have cheese or yogurt. Virus is maybe debatable.

As the topic's OP..I set no ground rules except that everyone's opinion is welcome. I simply put the topic out there for some lively discussion, to which we as earth bound, non science experts simply have speculation. This conversation is going just as I hoped. Carry on, and enjoy the discussion

This is what I am talking about.

The search for extraterrestrial intelligence (SETI) is a collective term for scientific searches for intelligent extraterrestrial life, for example, monitoring electromagnetic radiation for signs of transmissions from civilizations on other worlds.

The claim was that life means something that can reproduce itself and that's why I used bacteria and virus. We are not looking for those we are looking for intelligent extraterrestrial life.

I took the opening post and question of life to mean other beings like us for life on other worlds.

Ah! Now I know where you're coming from. I agree that intelligent life forms are far less likely than simple life to occur. But, the universe is so vast, that I wouldn't rule it out. However, the distances are also so vast that I doubt whether we will ever detect either one. I suspect it will be one of those questions that will never be answered. Of course, if someone were to invent warp drive???

Only under the right circumstances. Just think of it. Billions of persons have been born and died and no two exactly alike not even twins. What are the odds?

Well. So far in the immediate vicinity, zilch. If life was common elsewhere surely we would have found evidence on the moon or even on Mars. Of course Mercury and Venus are out of the question.

Warp drive? The top limit is the speed of light. The transporter is fun to watch but it's science fiction.

But no two alike? What are the odds of two being alike is my point. And then what are the odds of two planets being alike that can support life as we know it.

I know everyone takes the scattergun approach and says surely with all the millions of planets out there one must be similar to Earth and supporting life as we know it with intelligent beings.

But those millions are exactly the odds of that happening.
