The Emblems of Religion don't belong ... or do they?

[littlemanpoet]

Show me evidence that a soul or spirit exists - at what wavelength does it exist?

Sorry, can't help you there, since the soul and spirit are immaterial, outside of the whole evidence thing. Do you doubt the existence of love? mercy? justice? These also are immaterial, and the "evidence" for them can be explained by other factors every bit as easily as with soul and spirit.
