Like i said before according to many legends until 3000 years ago Mars was blue like Erarth.Maybe there was inteligent life on Mars but 3000 ago there was a desaster that distrioed it.The Cydonia constructions are another argument in favor of this theory.There is a pentagonal pyramid a face, a pyramid city and many other strucures that seem to be artificial in Cydonia.The cydonia area on Mars has many things in comun with the Giza complex and may be made be the same civilisation.Maybe Mars inteligent creatures came to Earth and influenced the evolution of Earth life and human civilisation.According to some theoryes humans came from Mars.

This is my artistical vision of the pentagonal pyramid and the face on Mars.
