I can comment on UFOs and aliens because.
1. I've had close encounters of the third and fourth kind so many times throughout my life I lost count starting at age three.
2. I was a moderator at UFOevolution.com, a now defunct Ufology board with members that were professional ufologists and authors as resident astrobiology, astrophysics, quantum mechanics, forensics, astronomy, meteorology, metallurgy, chemistry, and ufology polymath. I would question everything posted no matter which ufologist or author posted as moderator to debate them and others joining the debate. Unbiased and solely to get to the bottom of what's been happening to me to better understand it, studying the subject because I have no other choice but to believe what's beyond belief because seeing and feeling is believing.
3. Shadow people aliens accompany grey aliens and both are bad news so I question New Age space brother mumbo-jumbo and the stupidity of SETI, the Internet is as good a place as any to warn stupid people.
Grey aliens are much like us and just as fucked up as humans, shadow people aliens are not like us in any way other then humanoid form only super predatory and made of baryonic dark matter making their physiology incapable of digesting humans so they don't eat us. I know because they told me, only asked them one question about what they're made of and do not want to speak with them.
