Aliens have invaded, but what's your view?

I think that there are aliens, out there, somewhere. I wonder, if Earth aliens will take the place of humans, within the next 1000 years.

I can't comprehend that out of the billions of galaxies in our universe, there is only one planet that can support life. Now, as far as "aliens" go, we have no idea if they are intelligent or unintelligent. In my opinion it's highly likely that most other life in the universe (if any exists) is probably on the microscopic level.

It would suck if we found a way to travel to distant stars and meet intelligent aliens we could communicate with only to find out they are just as mean and petty as us. I would also be disapointed if they were less advanced than us.

I could see the human race going to an alien planet only to try to take over their market places with human made products and to convert the aliens to earth born religions. Our government would be pushing the American way of life and jesus on any race that could say how much and ahmen.

The odds are overwhelmingly in favour of aliens both existing and visiting our world.

And I think that if they found a way to get here than they must have overcome the same crises that mankind has yet to overcome. Which means they are almost certain to be benevolent.

We do not know the odds of aliens existing and we do not know the odds of them visiting Earth if they do.

To visit every star in the galaxy using above-current but entirely possible technology (say, a fleet of Orion drive von Neumann probes zooming around at c/10 and making copies of themselves at every stop) would probably take the best part of a million years (it doesn't really matter whether or not we restrict our searching to planets that look like they're life-bearing, the travel time from one end of the galaxy to another is very long). Call it a couple of million to get the results back to Earth. And unleashing a von Neumann fleet would be very rude to any potential neighbours. ^^ It'd be an impressive species that could stay coherent and focussed on the job that long! To get the job done quickly you'd need some kind of drive working off new physics - that's possible, but not something we can put odds on. To reasonably expect to be visited by aliens without invoking FTL drives, the density of life-bearing planets in the galaxy needs to be quite high, I should think.

LOL! Now this is what you call WrongPlanet.

But I doubt that would ever happen though, maybe it might in many centuries to go, who knows when?

I believe that there very well could be life on other planets. We may never know about it, but that doesn't mean it isn't out there.

Haven't seen or met them yet. If you have, tell them there's beer in the fridge.

And to bring me one too.

They'd better be interested in music!

So long as it's the right chirality... or was that the left chirality?
