"I would say that false theses are well worth reading and can lead to the establishment of new theses, I think I understood you to mean something like that."

Yes, that is what I mean. Only the ability to falsify a hypothesis can enable it's potential veracity to be ascertained. Nothing can ever be proved right, but being able to be proved false through specific predictive power can show it could be right (if it isn't proved wrong and successfully predicts something), which is the best science can do.

"...everything earthly is subject to the earth's electromagnetic field and that those creatures in which such a field can be measured interact with each other and with the earth's field and influence those creatures that do not have their own measurable field..."

This hypothesis is that there is one consciousness. Since consciousness appears to be separate individual experiences, it would be necessary for some kind of internal organization within that uni-consciousness to enable that apparent division. If consciousness is strictly such a collective, however, what does that mean for species like us that generate magnetic fields?

Without some specific prediction that can be falsified, it is impossible to verify whether or not there is merit to this idea. Because it is impossible to falsify, it cannot be considered a scientific hypothesis. That doesn't mean it's wrong. It just cannot be falsified and can only be a matter of faith, believed or not.
