Crazy enough, the Bible wasnt written all at once. The Bible was written over a span of approximately 1,300 years (depending on your historical, linguistic, and theological beliefs of course).

• The Old Testament, also known as the Hebrew Bible, was written between approximately the 12th century BC and the 2nd century BC.
• The New Testament was written in the first century AD, from approximately AD 50 to AD 100.

So probably a bit of the old testament could have been written while under the influence of mushrooms as that's when we were experimenting with wild mushrooms.

But what do I know, the picture says I died from mushrooms.
