There's countless planets out there, and from what scientists theorize now, life isn't all that unique, it could very well be common place. What kind of life? Aliens sitting on their sofas watching Here's Comes Gorlack Boo Boo? I hope not. Have they visited Earth? I really doubt it, why would they. We're a pretty unremarkable warrior species. I would think life intelligent enough for interstellar travel would avoid us. Or build a bypass.
That's not a dodge, that's just the state of the issue.
We can't rule out that there are intelligent civilizations within a dozen or so light-years of Earth, to say nothing of the rest of the galaxy, not to mention the hundreds of billions of other galaxies and all their stars and planets.
On the other hand, there are no definitive indications yet that such exist.
Yes, it exists...we are their experiment. They watch us closely, no doubt with great dismay.
That's interesting actually. There was a hypothesis years ago, that maybe we are nothing but a speck on some lint on a button on someone's coat.
Anyway, an experiment for a species of intelligence so much higher than ours. Like we experiment on mice. Or an intergalactic game show. It's fun to talk about.
I do think any species that has interstellar travel is so far advance from us, they would stay clear.
Yes, I’m fairly confident that there is sentient life, and I strongly suspect that some of these life forms are intelligent. As I argued on numerous occasions here in C-D, I think that life and intelligence are emergent natural phenomena, and given the high numbers of probable earthlike planets, I’d say the odds are very much in favor of alien life.
And, BTW, here are some related articles you might like:
There might be earthlike planets nearby, circling red dwarf stars. Red dwarf stars make up 75% of the stars in our local neighborhood, and data suggests that about 6% of them are likely have an Earth-sized planet in orbit. http://www.universetoday.com/99784/e...all-around-us/
Certainly life could exist on other planets. we really have no way of actually knowing until some form of life actually communicates with us. Of course there are a few folks out there who believe they already are visiting and communicating with us. However it's all speculation at this point. Perhaps we will find something on mars.
If the universe is infinite, anything that can happen will happen and, moreover, it will happen an infinite number of times. We exist therefore intelligent aliens must exist. This is not speculation, this is mathematical certainty. The question is then: how far away is the nearest example? It could be 10 light years. It could be 10,000 light years. It could be 10 billion light years. There is no way to know at present. It may take thousands of years of interstellar exploration to settle the issue.
