It is impossible to look up at the stars and not ask the question are we alone? It would be arrogant to assume that we are the only life forms in the universe but if we do have extra terrestrial neighbours, they must be more technologically advanced than us and may be able to communicate without the need of being physical present.
If you are prepared to consider the existence of aliens, should we assumet that it is safe to contact them and how should it be attempted? There are many more questions, with no certain answers so we proceed with caution. Although the aquisition of our native language is in most cases automatic in childhood, we cannot assume that communion with alien intelligence will be spoken.
Attempting to use the brain as a sending device for communicating with alien life forms is nothing new. How accurate we find it to be remains to be seen, or heard. Whilst there are many that claim contact, we are looking for objective evidence as proof of communication. So far our results are slim and do not constitute evidence.
