How does life come from non-life?

It is estimated that life began between 4.4 and 3.5 billion years ago. The origins of life are known to have come after the presence of liquid water on Earth. How life began in the waters of the Earth is still up for debate. One of the earlier theories was biopoesis. It states that the early oceans of Earth, which would have been much different than ours, would have held the necessary chemicals and conditions to allow the building blocks of life to form. Generally, someone suggests a lighting strike or a reaction with the sun’s UV rays as the “spark” which would have set off this reaction. The theory was helped somewhat by an experiment done by Stanley Miller and Harold Urey. These two scientists created a closed environment they believed similar to the one on Earth before the beginning of life then subjected it to a spark. Within a short time, more complex molecules had formed from reactions between simpler chemicals.

There are of course holes in the theory, and there are other theories to research and find out about. I encourage you to research them if you are truly interested.

@ Mr. Plankton, The moons and other planets in our solar system do not have the proper conditions to support life as we know it. They have many vast differences, most notably the atmospheric differences and the absence of water. As I stated earlier in my answer, water was essential for the beginning of life on Earth.

Not in a trillion Years....They say moons and planets have existing millions of years...yet no sign of life.....

I don't know what makes these scientists think like that....but am pretty sure they are Richard Dawkins ball lovers...and Richard Dawkins is Darwins stunt money! ;-)))
