No one I have ever heard of claims that life will end in 12 years. Some scientist have made the rexent claim that the Earth has about 12 years to reverse global warming or nothing we do will be able to stop it in the future. That's a bit different.
"Mars is part of the moon" Ive never heard of so I cant speak to that.
I have heard people make some pretty outrageous claims about Obama right here on this website. Things like Obama is planning to confiscate all weapons, put conservatives in FEMA camps, suspend the Constitution, declare Marshal law, refuse to leave office, institute Sharia law, etc. etc.
Why anyone could consider any of that true is beyond me. Today those same people believe that Trump is a genius, that hes playing three deminisional chess and trolling liberals when he speaks outrageous nonsense.
Some people refuse to accept reality and instead try to create their own false version and then become angry and desperate when true reality starts to encroach upon them.
