The consciousness through which three-dimensional terrestrial earth human being exists of is not created solely through a corporeal body.

It's ignornant and considered wishful thinking by those more endowed, that it would be that simple.

People have been astral traveling, using telepathy, psychokinesis, and all other "higher faculties" of the mind, which are suppressed and ignored through solo-western thinking.

It's fairly easy to do so, as it's the nature of human-kind to act a like a human, which is a multi-dimensional being, and not only existing of one corporeal three-dimensional physical body.

If you deny the claims, then you are speaking for the person and thus what you would call in blind faith that you know their experience, while the person themselves is speaking from their grounded and personalized experience of reality. If you haven't experienced that or any form of that reality yet, it's because you simply don't want to. Period!
