      Some say the big bang theory (not the TV show) created life, others may say God created the world in 7 days… what do you reckon?

      I believe that life began after the universe was created in the Big Bang. How life then started after that happened makes my head explode a bit – try reading this article and see what you think! http://www.bbc.com/earth/story/20161026-the-secret-of-how-life-on-earth-began

      Again one this is an easy one in that the answer is WE DONT KNOW

      but scientists have some ideas about ways it might have happened

      Some scientists think that life started by RNA (similar to DNA) forming as molecules of carbon,oxygen, nitrogen and phosphorous reacted and joined together in different forms. Somehow this RNA got inside a bubble of fatty material (forming a membrane, as we know these can form naturally).
      As more RNA entered these primitive cells they began to get bigger and split into smaller cells which in turn grew.
      But at the moment these are only ideas and nobody has managed to create life in a lab or experiment (although they have managed to make parts of cells)
      However with the excitement of finding more and more planets that could have life on them there is a lot of interest in this subject again
