Mars is called the Red Planet because of its reddish (21)…………….. There have been many explorations to Mars by humans since the mid-20th century. Scientists hope that we can find another planet to (22)…………………… human life.

              There are major reasons why the (23)……….. on Mars is unsuitable for human life. Temperatures on Mars can be as low as -87 degrees Celsius and rarely get above 0 degrees Celsius. But the bigger problem is the lack of oxygen. 95% of the atmosphere is carbon dioxide (CO2), and this is (24)………….. to breathe. Moreover, there is no water on Mars even though scientists have found traces of it. Reason why we are be able to live on Mars.  (25)…………; as early as the mid-19th century, (26) ………… discovered that Mars had some similarities to Earth. A day on Mars is 24 hours, 39 minutes and 35 seconds, almost the same as a day on Earth. Mars also experiences seasons just as Earth does. However, the seasons are twice as long because a year on Mars lasts about twice as long as an Earth year.

A new study published in the journal Science shows definitive evidence of organic matter on the surface of Mars. The data was collected by NASA's nuclear-powered rover Curiosity. It confirms earlier findings that Mars, the Red Planet once contained carbon-based compounds. These compounds – also called organic molecules – are essential ingredients for life as scientists understand it.

The organic molecules were found in Mars's Gale Crater, a large area that may have been a watery lake over three billion years ago. The rover encountered traces of the molecule in rocks extracted from the area. The rocks also contain sulfur, which scientists speculate helped preserve the organics even when the rocks were exposed to the harsh radiation on the surface of the planet.

Scientists are quick to state that the presence of these organic molecules is not sufficient evidence for ancient life on Mars, as the molecules could have been formed by non-living processes. But it's still one of the most astonishing discoveries, which could lead to future revelations. Especially when one considers the other startling find that Curiosity uncovered around five years ago.

Question: Have there been enough evidences to confirm the existence of life on Mars?

A. Yes, there have

B. No, there haven’t
