It's always been a mystery, although many do speculate, that aliens walk among us. Some have left their mark by using crop circles to communicate a message to us and others have had direct contact with other civilizations.
The Wandjina Petroglyphs are a perfect example of this. It's odd really. Today we tend to describe these extra terrestials in the way of small heads, a flat mouth, and no nose. However, according to Aboriginal mythology, if these creatures were seen with no mouths, the rain would never end.
Wandjinas are believed to have made the sea, the earth and all its inhabitants.The existing rock art found, has depicted them as having huge upper bodies and large heads. Their faces show eyes and nose, but typically lack mouths. Around the heads of Wandjinas there appears to be lightning and feathers. The Wandjina is thought to have special powers and if offended, can cause flooding and
intense lightning. The paintings are still believed to have special powers and
therefore are to be approached cautiously.
