Meteor showers

Geochimica et Cosmochimica Acta have published work pledging for a new theory on how life came into existence on planet earth. The team investigated meteor rocks from around the world and heated them up (using a new technique pyrolysis-FTIR). The meteors produced many gases including carbon dioxide 6% and water 12%. Carbon dioxide causes global warming that led to liquid oceans. About four billion years ago the earth and other planets were struck by the late heavy bombardment (LHB), meteorites have therefore furnished the earth. The explanation of carbon dioxide making the earth warmer and water making the earth fertile is very acceptable. They were also able to calculate the estimated amount of water the meteors brought to earth. The gases would start to work and merge immediately. The gravitation of the earth made sure that these gases did not blew to Mars by the solar wind of the sun.
I believe this is a very interesting topic. The theory sounds very realistic to me because we can find a lot of meteors around the earth. It is always good to look at a certain topic using different points of view. The technology develops fast which leads to new theories. The world should start an international funding organization to support these kind of researches. Maybe we can learn a lot from these chemical reactions so that we can create oxygen or water in the future. Perhaps we should also be able to reduce global warming in the end. The more we know, the more we can save. The world is something very unique and by investigating the birth of the earth we made figure out how life started.
