Life is Sweet: Sugar-Packing Asteroids May Have Seeded Life on Earth

Meteorites containing sugar like molecules have been found on earth, indicating signs of the origin of life for our solar system. According to this article, the meteorite contained a significant amount of these sugar like molecules, indicating that life started in space billions of years ago. They also state that the earth billions of years ago, was dry and harsh, hence, reducing the chance of observing water and organic compounds enrich life on earth. However, although arguments have been made to support that life originated from space, other scientists speculate that perhaps earth contaminated those asteroids found in our solar system. One example of such a controversial meteorite is ALH84001, a meteorite that was found in Antarctica, and remained intact since it had landed. http://www.space.com/scienceastronomy/planetearth/meteor_sugar_011219.html
