Grant Cameron - Government knowledge of alien contact

If you took all the mass from all the people on the earth it would be about the size of a grain of rice. That statement puts into perspective the floating through the wall scenario that the abductees claim to have happened. It also explains why they can not be seen if they don't want to be. So you know that someone is watching you but you can't see them.  And for us humans to wrap our heads around interdimensional beings or alternative universe or multiverse is a pretty new concept and so damn near possible to understand.
