yea thats exactly this

but still yes u theorically "exist", but how can you prove it?? many people dont beleive in aliens, so they may not exist, for em in any case. if there are really some aliens evoluated and everything, still they exist only for them. hope u get my point.

oh and donniedarko, yes from my opinion life is meaningless. even if there would be a god, even if we would be spirits, all this comes to an end, and if it does not end, whats the meaning anyway? and thousands of years ago, we were maybe what, 3-4-5 millions on earth. now were almost 7 billions. so if your spirit is changinf from a body to another, what are all the new ones? but yea i really think life is meaningless. i mean we could all die, the whole universe could explode right now, and seriously i really dont see the difference it would make. we are a drop of water in an ocean. if this drop dissapears in the ocean, who will know it anyways? and what would it change?
