I highly recommend you read the first 10 verses of Genesis very, very carefully. Pay close attention to the use of upper and lower case with words such as earth vs Earth, heaven vs Heaven, day vs Day. Use Strong's Hebrew dictionary to assist you in understanding just what this means. When finished, read Oxford mathematics professor, John Lennox' book called Seven Days that Divide the World

A caveat: If following this recommendation proves to be too much of a challenge for you, then on religious subjects of this depth and importance you should do the right thing and STFU.
