Physically, life has limits.
Intellectually? Depends on whether knowledge is finite?
If humans "meet" other worldly "creatures", it will most likely be more an intellectual, rather than physical meeting?
What would a more advanced civilization, or intellectual "being", communicate to us? Avoid climate change, be truthful?
Such a being most likely would try to communicate with us through telepathy. But how would we understand that "being", if the "being" only planted seeds of thoughts in our consciousness, and left the decision up to us (as in Startrek - not interfering in "untouched" civilizations)?
