Do you believe in any of the following?

UFOs

Ghosts

Life after death

1-7 are possibly real.

8-10 are less likely to be real. 

1. UFOs: If you mean flying discs made by extraterrestrials flying around our planet, then no.

2. Ghost: No.

3. Bigfoot: No.

4. Yeti: No.

5. Sea monsters (Like Nessie or Champ): I'm sure there are creatures swimming around we haven't encountered/documented yet, but other animals or whale blubber/whale carcasses for example often get mistaken for sea monsters.

6. Life after death: No.

7. Life on other planets: Yes.

8. Time travel: Depends on how you look at it. Astonauts technically time travel, so...

9. Atlantis once existed: It's possible.

10. Area 51 has hidden alien technology: No.

IIRC, there are bits of physics that allow for time travel. So yes on 8, though I highly doubt anybody has ever actually managed it.

No on the rest.

I do regard some as more likely to be true than others, though. In order from most to least likely...


3, 4 and 5 - we know life exists on Earth, there's nothing inherently impossible about Bigfoot, Yetis, and sea monsters, they're just really, really unlikely.

9 - Depends on what you mean. There is no "lost continent", certainly. But a coastal city, or a small island with a city on it, that was destroyed in an eruption or other disaster? Sure, I can believe that. Many people thought Troy was a myth until Schliemann found it in the 1860s, after all.

7 - Again, life exists on Earth. It therefore is possible that it exists elsewhere.

1 - I assume you mean UFOs as alien craft, not literally "are there flying things that are unidentified". If alien life does exist, it must also be possible that said life can and does travel to Earth. I find it very unlikely, though.

10 - Really follows on from 1. If you accept UFOs then it's possible that one crashed and possible that we got hold of one. Again, very unlikely.

2, 6 - Impossible, by what we know. What we know may be wrong and they may exist anyway, but as far as I'm concerned they're essentially all but ruled out.

1) No, not in the sense most people mean it.

2) No

3) No

4) No

5) No

6) No

7) Yes

8) Yes

9) No

10) No

Just to be clear, time travel in the Dr. Who or Back to the Future sense is bullshit, but we've proven time dilation is real, we know funky things happen to spacetime under the influence of extreme gravity, and "time travel" into the future is a matter of preservation.

For example if you're on a starship traveling at .99c, the clocks on your ship are practically stopped compared to the clocks on Earth. Time dilation used in conjunction with cryopreservation could one day make it possible for humans to live thousands or tens of thousands of years -- but we would only subjectively experience a small fraction of that time.

The intelligent life in the galaxy question is a whole other discussion of Drake's equation, the Fermi paradox, galactic timescales, and whether we're even looking and listening the "right" way for an alien civilization. We've been capable of looking for signals for less than a century, with is 1,000th of an eyeblink on galactic timescales. 

It it would be like getting a millisecond glimpse of a crowd of a million people and saying, "Nope, Waldo ain't there, I didn't see him."

Id say yay to most honestly.

The only I really believe is number 7. Something simple like a bacteria would be considered life and it's possible that something like this exists on our solar system alone. I think it's almost a certainty that life other planets exist when one considers the size of the universe. I don't believe aliens are currently visiting us or that Area 51 has hidden alien technology.

Sea monsters, Yeti and Bigfoot are animals that I find unlikely to exist. We can't find any conclusive evidence other than shaky footage... Not single dead body. Okay I might give the benefit of the doubt to the Yeti because it supposedly lives in a remote region but Bigfoot? Highly unlikely. 

I think Atlantis might be based on actual disaster that happened like the Minoan Eruption or something similar but I doubt there is a literal Atlantis. 

Time travel to the future is possible due to the effects of time dilation although we lack the technology to do so. Travelling to the past seems highly unlikely to me but it can't be completely ruled out. 

Ghosts and life after death: I don't believe it. I believe when we die, that's it. 

There's no way there isn't life on other planets.

Also, there are a number of plausible candidates for Atlantis, but Atlantis would be a fictionalization of someplace that had a catastrophic flood or eruption etc.

Re the rest, I like the fantasy of that stuff and I wish it were true, but I don't believe any of it.

And the idea of time travel is simply incoherent (well, aside from the possibility of exploiting relativistic differences in the passage of time).
