Photographs taken from Earth-orbiting satellites show small, ice-filled comets striking Earth’s upper atmosphere at an average rate of one every three seconds.a [See Figure 34.] Each comet adds 20 – 40 tons of water to Earth’s atmosphere. If this influx began when evolutionists say the Earth started to evolve, all our oceans would have come from small comets. No doubt past impact rates were even greater, because the planets have swept many of these comets from the solar system. Therefore, small comets would have placed much more water on Earth than is here today. Obviously, this did not happen, so oceans look young. [See also pages 320 and 330.]
