(But there is no actual evidence that they are dead.
Not one shred.)
Nor any that they are alive. This is not TV. They did not find a hidden island with a large supply of food and weapons.
Any plane crash into the sea or into land usually involves total death of all crew and passengers. Any crash with survivors would have required rescue within 48-72 hours to save anyone. I think the time of acceptance of a reality has come.
But there is no evidence of a crash!
I’m sorry, but I’m going to have to direct you to this post:
“No, there isn’t.
There is only evidence that their current location is unknown.
It is indeed possible that they are dead. It is indeed possible that their plane flew into Michelle Obama’s butt.
It is indeed possible, though not probable, that they flew through a rip in time and are 15 minutes in the past being menaced by Langoliers, and that they will fly their plane through the same rip and end up 10 minutes in the future, where time will catch up wit them at an airport in Bangor, Maine.
It is indeed possible that they were abducted by aliens.
It is indeed possible that they folded time and space, and instead of traveling from point A to point B, they are now lost in a dimension of Hell.
But what they are, beyond any shadow of a doubt, is lost.”
