There could be other intelligent species out there, but they haven't made contact or did and ran away in horror.

Almost without a doubt we are not alone. I would guarantee you that life is inevitable. A lot like how crystals "grow" under the right conditions.

Probably not.

If you consider the vastness and obscurity of the universe, then the chances that we are alone in it is pretty damn slim.

Very unlikely, in my opinion.

dunno if its worse if we are, or if we aren't and were really dumb compared to them

Without a doubt, we are not.
But, who we think are aliens visiting us, most likely are our futuete descendents.

Probably not, but contact may be unlikely.

Probably not, considering our universe might not be the only one in existence. In fact, scientists have recently proved that an atom can exist in two places at one time, inferring the possibility of a multiverse.

no way the universe is just to big not to have other civilizations out there

Statistically highly doubtful

I think it's impossible. There is just too much out there for Earth to be the only planet with some form of life.

Of course not,,,it is so unlikely we would be the in the only place life happened.

Thank you guys, thank you for your ideas...

When you consider that "life" increases entropy, then the odds of there being life on other planetary systems is more than likely. So out of many possible life systems there is also a probability of intelligent life somewhere else. I just wouldn't be holding one's breath waiting for some contact in the near future though.

Considering that there are actually many stars with planets orbiting around them, there is a very good chance that there is intelligent life outside of our own solar system.

It would be an awful waste of space if we were the only beings in the entire universe. I think the best guess is the easiest answer. If there were life on just one out of a billion planets then there would be life on billions of planets throughout the universe.

There are 300 billion stars in our galaxy, and 300 billion galaxies. Most all stars have planets.
WE ARE NOT ALONE !!!

I don't think we need to look as far as the entire universe.
Our own galaxy is so vast there could be intelligent life all over the place and we might never know about it simply because they are so far away.

This is, in principle, an answerable question. First, when the WEBB telescope goes up, we may be able to narrow the search to exoplanets showing atmospheres with free oxygen or other signs of metabolic processes.

But then there's the science-fictiony path to an answer. Draw a line from roughly Bombay to Stockholm, about 1,000 miles wide. Before the age of exploration, and I know there are plenty of exceptions, people west of that area were mainly animists or had animalistic or monstrous deities. People to the east had dharma, karma, and ancestor worship But people inside that area had human-appearing gods with human attributes. This zone was also the high-tech zone: alphabetic writing, the wheel, the horse collar. And let's not forget the Baghdad Battery. Just look at a sample of technology referred to (maybe) in Enuma Elis, Gilgamesh, and Genesis. Surgery with anesthesia. A radio. A tethered satellite with an escalator. A space shuttle. I'm certainly not proposing an ancient astronauts paradigm, but it is a good place to start looking.

Most likely not. There are almost 1,000,000,000,000,000,000,000,000 stars out there. If one in a trillion of them supported life, that means there would be life on a trillion other planets. The spacing of planets around the sun is almost in proportion to a fibonacci sequence. It's likely that that is the case in other solar systems too. That means a significant fraction of solar systems will have a planet at the "sweet spot" between freezing and boiling which would support life as we know it. Plus the fossil data shows that life sprung up pretty quickly on earth. We should expect the same on many other solar systems.
