hmm. If UFO's are real, then with the current technology we have we would have more evidence about them. we would at least detect them in space before we even see them on earth. no one has living proof that these "aliens" do exist, just a lot of stories from people and that cannot be 100% trusted
"what makes you think we don't have evidence?" says devil's advocate.
question is, is there any actual, factual, material evidence that suggests that perhaps such things does exist?
photos can be photoshopped, sounds edited, and the list goes on.
what truth is the question i'll next ask
Although this has been going on for 40 over years, with absolutely no result at all apart from a false alarm in which a dying star was emitting intermittent light, this is because the galaxy is so wide and vast that it will take many, many light years for the signals sent by us to reach the other planets.
You know... Aliens have to be technologically much more advanced than us to be able to travel to Earth.
If we're really living in an Einstein universe, it wouldn't make sense that aliens are able to travel to Earth from their distant galaxies at speeds near the speed of light. According to e=mc2, if you travel at speed of light with immense energy, your mass will be infinite and it's unthinkable that you can reach infinite mass without something happening. Also, if I didn't remember wrongly, the nearest star from the Sun is 4.4 lights year away, and mind you, 4.4 years if you travel at the speed of light.
So... How do aliens travel to us then?
As for the Sumerian topics, I don't see any links with aliens.
