Extra Terrestrial Life

To shane97:

One part of UFO's could be visual atmospheric effect or clime changing effect. Others might my high tecnology yet not shown to the pubblic. For examle, why UFO's seem to be somehow changing in design as design is changing in our world?

Last possibility are visitors from other paralel dimensions, seems more probable that visitors from other galaxies/ or stars from our Milkway.

I think it's highly probable that there is life on other planets somewhere, even possibly sentient life.  But I'm totally skeptical that any of it has visited our planet.  People just don't seem to understand the incredibly vast distances involved in our universe.  The nearest star to our own sun, Alpha Centauri, is 4 light years away.  That is, if you were traveling at the speed of light, it would take you 4 years to get there.  Alien life is subject to the same laws of physics as we are, so if aliens on a planet revolving Alpha Centauri were somehow able to develop travel at the speed of light, then they'd still have to pack enough oxygen, food, water, or whatever for four years of travel (and then enough for another four years back).  Unless they're freezing themselves (like in the movies 2001 and Alien) it would be hard to travel such long distances.

Another problem is that the UFO crowd always has the idea of all alien cultures being far more technologically advanced than we are.  Who's to say that life on other planets is sentient for one, and secondly, has evolved past the point of being cavemen using primitive tools?

And the last problem with the UFO crowd is that as soon as someone sees a strange object in the sky, it's automatically assumed by them that 1.  It's a spacecraft, and 2. It's extraterrestrial in origin.  Just because we see something flying in the sky is not a reason to jump to these conclusions.  There are plenty of strange terrestrial military aircraft which were assumed to be UFO's when they were still in the classified testing stage.  Sightings of strange craft around Area 51 and different military bases which house units flying UAV's (unmanned aerial vehicles) are common.  So just because something strange is spotted doesn't mean it's a spacecraft, that it's manned, or that it came from outside our planet.

Not to say that aliens aren't visiting us, but the actual evidence seems less than convincing to this skeptic.

The answer is yes an undisputable yes, i have had 2 threads blocked for providing evidence to this effect so ifor now i wont here unless more evidence is required.

Thats rich coming from you, i see you soon abandoned the other threads when it became evident how ridiculous you are.

Are there any ancient aliens playing on chess.com?

I abandoned your thread because, I didn't want to start feeling sorry for you.
