Actually, at this point it would be considered a hypothesis. Once we find a way to test the hypothesis and have it confirmed it might be elevated to the status of a theory. Do you have a method for testing for the soul?
There is no scientific theory of souls. How would you measure souls? How would you detect their presence? If you can provide me with a "Soul-meter" then I will gladly do some experimental work and derive a theory of souls. Until then, souls will have to remain in the realm of theology and philosophy and stay out of science.
[Ichneumon:] "Define "soul" as you are using it in this question, and I'll take a stab at it."
[Just mythoughts:] Hebrew word nephesh -soul- life as used "breath of life".
Ooookay... Could you be a bit more specific? This is so vague that it could mean any of the following (or something else entirely:
1. Oxygen metabolism.
2. Air-breathing.
3. "Vital principle".
4. Consciousness.
5. Self-awareness.
6. A form of "self" which allegedly persists after death of the body.

[I have yet to read one offering by an self identified E describing the E's theory of the soul.]
Nonetheless, your failure to discover such discussions is hardly support for your insulting claim that evolutionists "are completely obsessed with their flesh".
