Do you think there is Extraterrestrial life?
it is hard to know particularly since these hypothetical life forms may range from simple unicellular or civilized life
I think it would be a huge impact on our society just to find unicellular life
yes, that is true, and if much more advance life existed why haven't we hear more from them if they are capable of interstellar travel
I think we are so limited by how far in space we have communicated information, why wouldn't they?
Have you heard of the Fermi paradox in the apparent contradiction between the high probability of allien life and that we have not been visited by them?
I have heard of it.  I think one of the possible answers to it is that we just don't know that we have been visited or that messages are coming
Sure, or about the great filter that as I understand it argue that maybe life is much more improbable than stated by scientist?
