Unless you are a Biblical scholar and have read the Bible in its original languages (and understand the contextual subtleties in those languages), there is no way for you to know exactly what God said.
The corollary to your argument is that God has lied to you - yet the Bible clearly states God is incapable of sin and can not tolerate it in his Holy Presence. Don't bother replying - I can guess that your going to tell me Genesis is mostly myth and fable and recorded by mere man therefore full of error and mis-interpreted statements. Hardly!!!
It depends on the context. The purpose of the Bible is to provide spiritual direction. It interacts with history but is always looking at the soul. Thus from a spiritual basis one gets the message pretty clearly: God created the Universe and filled the void. Man was pretty late in the game. Man is here to love God. Woman and Man are for each other. And the whole thing is about Love. Lingustic subtelties don't matter at that level. And in general, the framework established by Genesis is, IMHO, quite correct. But scholar's can't even agree on the original language use of the word "day" in the original language.
Jesus studied the Bible and affirmed the old testament - Please please please try digging a little deeper into your faith rather than relying on worldly experts and their opinions.
Jesus did indeed affirm the Old Testament. It is the foundation for His work and words. But by saying "yes, all that is correct" doesn't add clarity, just authority.
I mean, there are two versions of The Ten Commandments! The Bible contradicts itself "factually" all over the place. Even the story of the road to Damascus has two different versions (which gets worse when read in the original).
This isn't God lying to anyone. It is using a spiritual guide to address non-spiritual matters.
God created all the languages (see tower of Babel) so I firmly believe that while minor things can be lost in translation nothing which God has wanted mankind to know has been lacking throughout the ages. He states that His laws are written on our hearts - therefore no matter the interpretation of the 10 commandments mankind knows intuitively not to steal, kill, lie, dishonor God nor parents, etc.
Does it really matter what scholars and experts say or doesn't the clear language in the Bible define a literal day ('there was evening and there was morning')?
Here's something to simplify it even more. My late uncle - John - was mentally retarded from birth and never exceeded the intellectual capacity of a 5-6 year old yet he heard enough of the Bible and believed in his heart that Jesus was the Christ, the Son of God and accepted Him as his Lord and Saviour. The Bible is also clear that when the innocent die - those not aware of their sins, those who have not reached a mental age of accountability regardless of their physical age - go directly to be with God in heaven. John was 49 years old when he died and only God could know if he truly reached a mental age of accountability. I know of and have seen very many 6-8 year old children confess faith in Jesus Christ - including my own adopted son, my own biological daughter, and 2 more step-children who I love as much as my own kids. We all need to come to Christ with awe and reverence and child-like faith.
Intellect can be a hindrance and detriment if you allow 'pride to go before the fall'...
