According to astronomers, the sun is shrinking (albeit very gradually). Its diameter is shrinking by a rate of almost 0.2 second of arc per century. This means that the sun would have been twice its present size less than ten million years ago. 100 million years ago, it would have made the earth’s atmosphere far too hot to sustain life. 200 million years ago, it would have touched the earth! How do these calculations reconcile with the evolutionist assertion that the earth is some 4.6 billion years old? Clearly, they do not.
