Did you know Jan there is life on planet Venus? Now, one needs to get out of the box to understand how there is life in Venus. Finding life on other planets requires a very simple process. Using just ...Colors. The primary colors of light is red, blue and green. The primary colors on earth is red, blue and Yellow. You have in fact two Primary Colors. One for Earth, and one for everywhere else. To search for life like that on Earth, you simply need to follow earth primary colors, red, blue and Yellow. So looking with a telescope from outer space you need to find three planets that are next to each other that are red, blue and Yellow. (the primary colors of earth, and life on a planet) Venus is Yellow. next to venus is mars, Red... and you got Blue. All three planets are next to each other. red, yellow and blue. If you find planets anywhere else in the universe, just look for 3 planets that are together with the colors red, blue and Yellow. -- The Starmaker -- To question the unquestionable, ask the unaskable, to think the unthinkable, mention the unmentionable, say the unsayable, and challenge the unchallengeable.
