OK this is going to sound crazy but i have weighed up some facts

1. Egyption hieroglyfics about death

2. All the dead people showing up everywhere

3. The fact that dead people can speak on jacobs behalf

4. Ben looked up into the sky and said ' happy now?'

IS JACOB THE EGYPTION GOD OF DEATH???

ALien activity sounds a bit far fetched, and we havent had any real evidence of alien eg: Ship wrecks and laser guns. and they would have been pointing that out to us by now....i think/ anyway i think the 'others' are from the future and were some sort of science research team that dicovered the orchid like 500 years into the future and accidently got transported back to the year 2004. ben was their leader. I also think the dharma team is from the future aswell. How this all comes together is BEYOND me haha.
