Interesting thoughts OP...

But most of your examples are early estimates after some disaster or another... So, most of the missing are accounted for in later updates. Whenever someone uses big, round numbers with lots of zeros it's not a real number.

I agree that people do go missing - for a number of reasons. Folk in the outgroups - like the homeless, low-caste criminals, and those in "undesirable" ethnic groups are often subject to extrajudicial killings.

And in big disasters like earthquakes, floods, tsunamis, etc... the human body just doesn't hold up all that well, so most of them just decompose without fanfare or a proper burial.

Another segment of the population decides to "go missing" every year... Maybe a number in the tens of thousands in the US have just had enough of wives, families, jobs, etc. - and just walk away.

So, anyway - an interesting idea, I just think your numbers are way off.

As far as the minor premise goes - that children are being eaten alive to give super powers to non-human entities... Sounds unlikely. Also the sources reporting multiple victims at a specific location - why are they covering it up - yet leaking it? Doesn't seem credible.

As far as the nasty railcars of death... I remember that rumor, and every time I've tried to track it down it was bogus. I'm happy to go look at suspicious railcars anytime - if someone wants to get up an expedition.
