Ghost Boat

I read this article in yahoo news (where i learn more from than in school) about a yacht floating off the coast of australia. here,s the thing, the boat was ompletely fucntional/functioning. The computers were all turned on, a laptop was left open and a meal was set out on the table with the food and utensils in place. there was no damage to the boat of whatsoever, no sign of it going through a natural calamity or an accident. in other words, everything was in place. except for one thing, the crew or no one for that matter was on the boat. how freaky is that?! what the hell happened to the people?!

I have three and a half theories as to what happened.

Theory 1. The people were actually deep sea diving and forgot to put the anchor down. so right now they're somewhere in the ocean without a boat. the boat must've floated away or possibly found at the time of the dive and was hauled back to shore leaving the people behind.

Theory 2. They were abducted by aliens.

Theory 3.a All of them fell off at the same time and had no way of getting back onto the boat.

Theory 3b. All of them were pulling a jack and rose scene when a big wave hit the boat and threw ll of them off.

So anyway those are what i came up with. what do you think? comment and give me some of your theories as to what happened. Let's have fun! hahahaha
