Our search for life on another planet needs to look for a light source that did not come from a sun. Humans produce light unlike the sun— If you can find a light source with this wavelength, you have found what we have been looking for---- Anyone agree/disagree?
Don't think it's that simple. Humans and natural sources (including stars of various sorts) put out all different wavelengths of electromagnetic radiation, clear across the spectrum - not to mention weird stuff like space stretching and gravity fields.
