Almost none of these are even close to mysteries. The majority are bullshit that mystery-mongering cretins keep pushing on gullible, credulous twits so they can sell more horribly stupid books/TV shows. Look most of them up on Skeptoid if you want to know the real story behind these.
those are not really the biggest mysteries
Some of these are straight-up false and known to be so. Others are legitimate mysteries. (The Bermuda Triangle doesn't really lose more ships than other places. There have just been more high profile cases, and so it keeps getting noticed more, and so people give more credence to it, and so on)
Some have substantial evidence, some (I believe) are works of fiction.
Most of these are mysteries if you're a smoothbrain with no higher cognitive function.
"The Biggest Mysteries of History."
Many of these so-called mysteries have perfectly reasonable mundane explanations, and the enigmas surrounding them have been largely debunked.
a lot of these are bullshit
Most of this crap has been explained....
This is dumb as fuck.
How can vile vortices be lower than the bermuda triangle when it includes the bermuda triangle? And why would they both be on the list? And why is the loch ness monster number one? I guess this list is a mystery in itself.
Interesting, but most of these aren't mysteries. For instance the Tunguska event was caused a meteor that exploded midair.
"Although some of these mysteries are only on the list as a result of their infamy"
Most of these aren't mysteries
