NASA scientist Jim Green has revealed that the U.S. space agency is closer to declaring that there could be life on planet Mars, but humans might not be ready for it.

"It will be revolutionary - it’s like when Copernicus stated ‘no we go around the Sun’ - completely revolutionary. It will start a whole new line of thinking. I don’t think we’re prepared for the results. We’re not,” Green, NASA’s Planetary Science Division director, said.

The NASA scientist also shared that it will only take a few more years before the space agency can announce their findings of possible alien life on the Planet although the space firm has been sharing clues that show off its very real possibility. First, it has been proven that there is a large area beneath the planet that holds liquid water -- a main component of life. There are also signs of methane gas, which is usually produced by live organisms beneath the surface of the Earth.

Now before the actual announcement of finding alien life on the Red Planet, we have to settle for now for some of the most outrageous claims created by alien theorists who believe that humans have been ignoring obvious signs of alien life in Earth’s cousin planet. These include certain rock formations that show there might have been an alien race who are carving and leaving clues that they really exist.

There are also odd surface formations that can make you believe some outrageous alien theories such as these “claw marks” found on a Martian desert. According to CNET, the image is quite perplexing if taken out of context.

Like all other images found on Mars that have been dismissed by NASA scientists as natural rock formations, they also explained that the “claw marks” have a perfectly good story behind it. The image was taken at the Hellas Planitia on Mars and located inside a massive crater that’s said to be deeper than the Grand Canyon and is already billions of years old. It was taken by NASA’s Mars Reconnaissance Orbiter and is said to be part of a “dramatic impact basin.”

NASA described the lines as "scratch marks," but they are produced by some giant alien that’s clawing its way into the desert. Per NASA, the lines are “linear gullies” which have been caused by dry ice breaking the surface into blocky shapes before sliding down the sand dune. The lines are actually the carved path the dry ice creates as it slides down.

The phenomenon is nothing new to scientists and NASA claimed that they have seen it in another Martian region although the lines are not as squiggly as the one taken by the MRO on Hellas Planitia.
