Can you splain to me how the Armies of the world are going to fit into that very small valley?

The entire population of earth could fit into Texas with plenty of room, so fitting the armies of earth into the valley wouldn’t be that much of a problem. After a while it would be even less of a problem.

A lot of the world's population will have been wiped out by then. If you read the book of Daniel, it explains that the world will be at war with each other. Throw that in with the fact that the world will be rife with plagues and judgements from God during the tribulation and you can see how no one would survive up until Armageddon except that God will spare a portion of the earth's population.
