I won't go into my whole thoughts on this subject.. just want to put this little idea out there.

The first law of thermodynamics, also known as Law of Conservation of Energy, states:

Energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

This means if our souls are made from energy, we are immortal.
