The infinite belief of Religion

How do you know I exist? Well actually you don't.  You have to observe me to know that I exist and then the energy which is aborbed, becomes part of you and I.  Therefore I am you and everyone else is me. We are all one and the same existence.  Thats if we exist at all.  All we can do is believe that we exist.

 If I can see a blind person that is talking to me, how did that blind person obtain the energy to communicate and assert their existence?  Did they obtain the energy from another blind person or did they obtain the energy through absorbing it through their skin?  If they did absorb the energy through their skin at what wavelength was it absorbed and how then was it transformed?

Perhaps, the blind person obtained the energy from a grain of sand in another galaxy and then travelled for an infinite length of time and space through an infinite number of dimensions.  Of course if the blind person cannot see the grain of sand how can the grain of sand exist?  The energy was created by our infinite belief which may or may not have travelled through infinite time and space.
