Hi,
Personally I think we have been visited by aliens already since a long time, maybe since 1920 or ealier, by my study and my influence from John E. Mack a respected psychiatrist of Harvard who did work on alien abductions from many victims or patients.
As an introduction to this community and knowledage base here you can see a credible UFO experience:
Personally I am interested by alien technology only, only for that, not overmore to help our society it might be good for you to do the same.
However this community suffer the same emotions than the cryonics community, to be ridiculous, shameful, weird etc...
So my question after some study of your part is, what do you think of that ? You can contact me by email: jonano@gmail.com thanks for your concern.
Peace and cheers,
--Jon
