Is there an extraterrestrial life? We will never get the answer until there is a proof. People always believe what they believe. Take an example of the recent image taken from the NASA spacecraft “Spirit” image achieve. The image shows what seems like a creature standing or walking at the ledge of the rocky cliff on the surface of Mars where the spacecraft landed on the planet in 2004.
Is it a life on Mars? or is it just a trick of image through the eyes? You may judge by yourself until we have further evidence.
