a hundred years is too much. We'll probably not even live upto 85 years, due to increasing pollution/environmental degradation.
UFO's, I believe, are a government conspiracy to cover up highly advanced technology. Area 51 is probably a "eureka" esk area of the government. If you don't know what eureka is look it up it's a sci fi show.
I believe UFO's are real. My mom has told me that she's seen one before. She said her and her ex-husband were driving in their car when it was dark, and a UFO showed up just above them and hovered there for a while. They stopped the car and her ex-husband got a flashlight out and shined it up at the UFO, and it vanished in the blink of an eye. People may think I'm "coo coo" but I believe my mom. She is not a crazy person lol. I also believe that we are not the only intelligent life forms in this universe. I mean, who knows how many other planets in other galaxies are inhabited by life. They could be much more advanced than us, because they could have inhabited their planet for much longer than we have. They would have more time to advance in technology and what not. Quite frankly it scares the crap out of me. Who's to say that they wouldn't test on us just like we test on other lower life forms like rats? But then again they may not do that. We don't know. Okay I'm done babbling now. I stated what I believe.
I think they're real. There's a great chance earth doesn't have the only living organisms in an infinite universe.
UFOs exist but I think there are too many pranks caused by people making it hard for others to believe in them.
I don't think aliens who are intelligent enough to travel through space fast enough to get to us would have any interest in a life form so unintelligent as ours
I guess if it's possible to travel at warp speed (n times C), then they probably do exist, but not many scientists believe that >C is possible.
UFO's actually visiting us? Fiction. Alien life forms, totally exist. The nearest life forms that have equal or greater intellegence as ours are probably light years on light years away and may never reach us. Or may have been extinct for millions of years before we existed. Who knows, maybe in 10 million years, aliens 10 million light years away will observe what we're doing right now here on earth and try to come visit us, even though we're long extinct
I'm not sure about them visiting us since governments are so good are covering things up and controlling media, but I definitely believe in alien life forms. The universe is WAY too big for us to be the only life forms it produced and it would be egocentric of us to think so. I also believe that probably human imagination can't conceive what shape they have...
