The source of this information is questionable but I am posting it because it is getting a tremendous amount of discussion on the internet and there have been some very reliable reports about structures on the moon!
Dr. Micheal Salla has indicated that there is a Military Industrial Extraterrestrial Complex or MIEC, and that Earth is being assimilated by an alien agenda which also operates on Earth's Moon.
The photo below is similar to many that I myself have seen. It appears that the Chinese who took the photo, have confirmed that aliens exist. The Chinese have probably been in contact with these aliens already.
That would explain why so many radio telescopes are searching for signals from aliens, and more being built as we speak, yet no reported signals from aliens were reported to the public.
