Hurtling in from space some 16 million years ago, a giant asteroid slammed into the surface of Mars and exploded with more power than a million hydrogen bombs. This caused huge quantities of rock and soil to fly into the thin Mars' atmosphere. While most of the rocks fell back to the surface, some of the debris, fired upward by the blast at high velocities, escaped the weak tug of Mars' gravity and entered into orbits of their own around the sun. Scientists believe that the earth's gravity caught some of the debris and pulled it into the earth. Scientist Digregorio, Barry E (B4) stated that inside the debris of falling

rock, were microorganisms. He notes

Scientists believe that the high surface temperatures on the dark areas of Mars may be explained on the presence of living vegetation placed upon a dry vegetable mold. Coblentz, a scientist of physics and astrology, created a theory that moss and grass might be a reason that the dark areas have a higher temperature than the layers exposed to the sun. Plant life would be "pinned down" because of the atmospheric pressure. Within the canals of Mars, the search for Martian vegetation continues. Further more, Goldsmith 12A , scientist of astrophysics, had found oxygen and water vapor on Mars.
