Some say they know that life began by an act of creation in the recent past. While it is unfair to say that they only 'pretend' to know this, it is a belief largely based on faith.Others believe that the evidence shows that life began many millions of years ago, in early pre-Cambrian times, when the Earth was hot and volcanic. Scientists tell us that life slowly evolved by natural selection to the point we have now. Once again, it would be unfair to say that evolutionists 'pretend' to know this, because there is so much overwhelming evidence in support of evolution.For more information, please visit: http://christianity.answers.com/theology/the-story-of-creation
