This is your opinion. Many other people, even in ancient times, understood it differently.
Who is God, YHWH or Science?
Do you envision some sort of conflict between God and science? I don't.
True science, no. Man-made reaching for anything-but-God-to-whom-I-am-accountable, yes.
The difference is not "this is my opinion" and "this is your opinion". What does the text SAY. It its normal natural sense, it is 6 twenty four hour days and I don't care if Moses himself wanted to muse about it. If he meant periods of time, there were words for that. When the Bible makes common sense, seek no other sense. It says 6 days, it means 6 days, it qualifies those days with morning and evening so they are literal days. This is true whether you call it "opinion" or not. It would be true if nobody believed it because God inspired the writers to write it. He was the eyewitness on the scene and should know how long he took to create the planet.
Unfortunately, I see you will not accept common sense and want to use the old out of "that's just your opinion." Sorry, it is what it SAYS. It may also be my opinion. But someone who wants to claim it says something other than 6 days is either blind or an idiot.
