First, 250 million years?? 65 million years?? I thought the Biblical calendar reaches to less than 6000 years. So from whence arise the millions of years? In my book, The Science Of God, I discuss in detail the age of the universe and the universal perception of time adopted by Genesis for the first six days, a view that sees the flow of events from the beginning, looking forward from a time when the universe (and in parallel time) was highly compressed. In essence, the 15 billion years of cosmic history compress into six 24 hour days, even as the hours remain 24 hours as we know them and the billions of years remain years. Einstein and the laws of relativity, a part of the divinely created laws of nature provide the explanation.
