I don't think that the gravity thing would do what you say it would. There are too many other outside influences that effect weight and mass in order for that to be true. However, I did like your statement before that =P~

I think that MM is the best P2P clan, not for sure though.

Agnosticism is more logical. Absence of evidence does not mean evidence of absence.

Technically, the person asking the question can only be sure of him or herself existing. You are correct that it is possible (but not likely or plausible) that we all be figments of your imagination. However, from my perspective, you would be a figment of my imagination. No way to get this question right because it is all of a matter of point of view.

Agnosticism is the only smart choice, imo. Both sides have too many holes in their arguments to boost it past the other. However, my belief system would be that of a Deist, which is like the middleground of a Theist and an Agnostic.
