sderenzi said:1. Just because people make personal comments doesn't really disprove their statements, this is a BS way the scientific community can justify anything. People were saying concentration camps were real but everyone was like "where's the proof of the showers being poisoned?" It's moot, people are saying something.
With regards to concentration camps there was probably aerial photography of the sites held by a number of governments, there were accounts from Survivors, accounts from the actual guards that didn't necessarily agree with what was being done or were haunted by what they had been apart of and the actual numbers of people that were unaccounted for after the war.
Evidence of the disappeared was found in the mountains of person effects, occasional findings of mass burials and even soil samples from such sites that did mass cremations could find a high levels of certain chemicals that are only found in/around burial sites.
2. Aliens could spread throughout the galaxy traveling at the speed of light in around 100,000 years. This isn't that slow an would easily allow them to find us. That's just around the length of time they'd need in order to build the type of technology which we see.
The real moot point is this whole Scifi perspective that mass can travel at light speed. In essense it can't and is suggested to be impossible both mathematically and in theory by many relevant scientists.
However this doesn't suggest that space can't be bent or manipulated to enduce the distance of travel, but such systems would require massive arrays to tap into the artificially created universal scheme which is not something you find the whole universe filled with.
3. You are right about the space travel, it's extremely dangerous. I wasn't entirely certain what the method was they used to come here could be. I have however thought about it an the fact these beings can actually walk through walls then abduct people in beams of light is a key. If they can phase matter or cause their ships to phase through it then travel in space would be less dangerous, more just a question of speed. An in fact we see people claiming that they can.
This is all stories people dream up. For years "ghosts" walked through walls, then Aliens became the popular fantasy so they now do the same. You should perhaps analyse what makes up a wall and what can penetrate it. For instance radio signals obviously can to an extent, however the greater the thickness and Density of the wall will lessen the amount of radiation that can penetrate.
Again such radiology to be controlled would and does require massive arrays and neural networks to process all the data of the footprint being analysed. Such systems would be useless light years away and would suggest that IF such apparitions were real then they are utilising very human systems and operated by very real humans.
