Yes there are benevolent extraterrestrials but they can do surgery and other tasks while you are asleep or holding still without abduction due to the advanced science they have. Abduction is a much more dark scenario than what an ethical being would do. And then you have mantid ETs reported to be standing over people's beds causing fear. In my opinion these are not beings with good intentions.Posted by Flash (here)
I agree with this, and they are most probably quite self serving.Posted by Omni (here)
The mind can be designed. This means an air of 'positivity' can be easily done to manipulate. Having dealt with a lucifer type of being in my life i am alarmed by the susceptibility of the comments here. Scary aliens that abduct and operate on you taking your sperm and ovum are not friendly.
Can there be the opposite as well? Beings that are service to others, like their little brothers for example? I believe there are. THey may not be those we encounter the most on our planet, yet i believe they exist.
Now, mark my words: believe. This means I have no proofs. Anything is possible.
