Stephen, let me ask you a question. Why does the Bible have to be inerrant to be useful?
This is from your own statement that if there was even one contradiction within its pages it would be of less use than a raindrop hitting the sidewalk. Yet there are plenty of contradictions within its pages, even besides the ones I mentioned
I'll grant that if you go to direct translations of the original Hebrew texts, some of those contradictions are resolved. For example, the contradiction between Genesis 1:20-21 (describing all living creatures being made from water) and Genesis 2:19 (describing them being made from the ground) disappears if you refer to the original.
However, the contradiction between Genesis 1:25-26 and Genesis 2:18-19 (oh, and 5-7) does not vanish.http://www.mechon-mamre.org/p/pt/pt0101.htm
25 And God made the beast of the earth after its kind, and the cattle after their kind, and every thing that creepeth upon the ground after its kind; and God saw that it was good.
26 And God said: 'Let us make man in our image, after our likeness; and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.'
According to this, God made the beasts of the earth before making humans. Yet, if you then go to Genesis 2...http://www.mechon-mamre.org/p/pt/pt0102.htm
5 No shrub of the field was yet in the earth, and no herb of the field had yet sprung up; for the LORD God had not caused it to rain upon the earth, and there was not a man to till the ground;
6 but there went up a mist from the earth, and watered the whole face of the ground.
7 Then the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
18 And the LORD God said: 'It is not good that the man should be alone; I will make him a help meet for him.'
19 And out of the ground the LORD God formed every beast of the field, and every fowl of the air; and brought them unto the man to see what he would call them; and whatsoever the man would call every living creature, that was to be the name thereof.
This actually reverses the order from Genesis 1, which had animals made before humans. Genesis 2 also describes birds being made after humans, when according to Genesis 1, they were made on the fifth day (verses 20-22). And on top of that, according to Genesis 2, plants had not yet been made, but according to Genesis 1, plants were made on the third day (verses 11-12).
In short, you have two completely different creation stories here, which directly contradict each other.
