When you study the Bible record, the nation of ancient Israel, how the Bible was put together, and the many things the Bible talks about, you will see that the Bible is truth.
Did you visit Israel yourself or only study acient Israel online and library? 
The earth and universe being only a little over 6,000 years old, and a universe in entropy as well, tells us that the ancients from the time before Noah and shortly after, had far greater abilities to think than we do. Knowledge about God and the creation was available to them, in writings and from their ancestors, even though much of it wasn't believed.
Knowledge about God abounded among people, even though it wasn't believed correctly. There was demon influence that twisted what the people thought they knew as history. The demons knew general basics of the plan of God for salvation of people. They twisted it, and implanted it in various religions that they helped wicked people to create. They showed the future (although imperfectly) because they knew much of what God had in mind.
All this is why there is partial Bible knowledge found in other ancient religions. Moses, at the time he was prince of Egypt, learned about this, and sorted it all out. God directed him to write the truth down in the first 5 books of the Bible, so that people would have a record of the truth.
----------
A note here: Plants like marijuana, but others that are a lot stronger, influenced the ancient peoples to contact demons. Then the demons they contacted influenced them to turn from the understanding about God and the truth. That's what demons do.
Stay away from hallucinogenic drugs. Because of entropy, your mind isn't strong enough to resist the demons as much as the ancients were able. You will only be dragged away from God, towards damnation by them (the demons) if you weaken the natural resistance of your mind by the use of drugs.
