Genesis "Contradictions"

"Did it take God one day or six days to create?""These are the generations of the heavens and of the earth when they were created, in the day that the Lord God made the earth and the heavens" (Genesis.2:4). SEEMING CONTRADICTION: "And God said, Let there be light: and there was light. ... And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day . . . And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day. Thus the heavens and the earth were finished, and all the host of them. And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made" (Genesis 1:3 - 2:3). EXPLANATION: The word "day" (used in Genesis 2:4) is a reference to a period of time (not millions of years). In science we use it to describe a "solar day"--a division of time equal to the time elapsed between two consecutive returns of the same terrestrial meridian to the sun. The Hebrew word (pronounced "yome") means "a space of time defined by an associated term." PLEASE NOTE: I am speaking at a church of 7,000 in Paris, this Sunday (I didn't know that there were 7,000 Christians in France)), so I may not have access to the blog. I return Tuesday (God-willing). Christians--I value your prayers. Atheists, please continue to think for me. Thanks.
