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, are they more technologically advanced than us apes and able to communicate without the need of a physical presence?
If you are prepared to consider the existence of aliens, is it safe to contact them and how should we attempt it? There are many more questions, no certain answers so we proceed with caution. Although the use of language becomes automatic in childhood, we cannot assume that our communion with alien intelligence will be spoken.
Attempting to use the brain as a sending device for communicating with aliens 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.
