Ufo's Real or Fake?

The human race must be arrogant to think that we are the highest Intelligent life form.. i dont believe that aliens have visited Earth but it doesnt meen they dont exsist.. They are out there.. but 2 far for them to visit  :P

We don't have to be arrogant, we just have to be.

It's a statistical certainty that aliens exist.  Have they ever visited Earth, on the other hand?  Extremely unlikely.

I agree with this. I didn't mean for my post above to sound like I didn't believe in the possibility of intelligent life on other planets. I just don't think they have ever visited Earth. Considering the immensly vast reaches of space, it is, as you say, extremely unlikely.

and thus i have to say i don't agree with your statement that other lifeforms have never visited our earth, if there are any out there. I believe there are probably UFO's out there, and so-called "aliens". the chance that there isn't is so slim. but for something to never have visited earth might be slim but it also might be huge depending on how you look. Earth has been around for a long time in our standards. Millions of years. Whose not to say that something has stopped here while the cavemen or even dinosaurs were here, hell, even before the dinosaurs  when our planet was being born. I have listened to people say that they don't believe that there isn't life out there, and i can see where they come from, but i think that there is life out there, and possibly life intelligent enough to possibly create something that could make it to earth. But, who isn't to say that there isn't anything else on this planet moving at our speed of light, walking through us unaware of us eh? there are just so many possibilities that people spend their life on such a topic

I really don't think you understand the vast time scales and distances involved here. Yes, the Universe has been around long enough for several intelligent space faring civilizations to emerge (statistically). But, there has also been enough time for those same civiliations to fall. AND, I do not believe there has been enough time for it to be statistically probable that one of those civilizations set out at around the exact time period they would have needed to leave in order to make it to Earth during our modern era. To use an analogy, it would be like threading a needle the size of an atom. They would have needed to leave some hundreds of millions of years ago... maybe longer. If they were off by even a few hundred thousand we would never know. Not to mention how they would even find Earth...

thus is true, but if a race has somehow managed to get close to light speed that time slows down for them relative to us, then they could possibly find us, and if that is the case, then they might have the technology to find a planet, and see it with the possibility of detecting life on it. We can only see galaxies and estimate at what we think might be a planet orbiting a star (by noticing a slight wobble in the star from the gravity of the planet moving the star), but who is to say that either of us is correct, we can only guess. Thats why science is amazing. but as even then, there could be something on earth right now watching us while they aren't visible to us. never know

That's... not quite how it works. Yes, if they are moving at relativistic speeds time for them would move slower than it would for us. But, on the scale we're talking about, they could potentially bypass our entire civilization in a manner of centuries in their time frame. With that in mind, and the fact that they would probably be spending much more time than that at those speeds (because of how far away they would be) it's just not likely at all. Plus, they can't use that effect while they're searching for our planet. They would have to find our planet before hand, or find all possible candidates of planets with intelligent life on them, and then travel to each one. That would increase the travel time immensely because for each planet they go to they would have to ramp up to near light speeds for the first half of the trip, and then ramp down their speed for the second half of the trip at the same rate (because otherwise if they stopped from near light speed down to zero too quickly they would kill themselves with G forces).
