A lot of scientists don’t think so!
How does science “explain” the existence of the Universe? You could describe it like this:
In the beginning there was an equation. The equation said that the Universe could exist – so it did! It just happened to have the right kind of stars, planets, geology and chemistry so that life could occur. Life was an accident, and the development of human beings was the result of evolution and more accidents. there is no purpose to our lives at all, and really no reason why anything at all should exist!
Is the scientists’ story satisfying? Of course not, but I’m not suggesting we replace this story with an unbelievable one about God creating the world in 6 days. To believe that would be to treat the Bible as a science textbook – it’s lots of things but not that!
What gives purpose to our lives is the faith that the Universe was created by God – who just is… – and after many billions of years, God’s Universe gave, by evolution, people who can love each other – and God.
