Archeology continues to uncover facts that support the accuracy and truthfulness of the Bible everyday.
Included in this - the dead sea scrolls - show that these writings from the old testament are accurate and were indeed written hundreds of years (approx 1000 if I recall correctly) before Jesus Christ.
Nothing about Psalm 22 is vague - some Bible students even think that Jesus last words may have been a full repeating from Psalm 22. Either way he uttered words from both the beginning and ending of Psalm 22 while he was being crucified. Furthermore, many of the prophecies about his life and death were fulfilled by others in His life - including the evil King Herod.
Maybe you should 'pull your heads out of the sand' before the time of your own demise...
