The most objective way of understanding history is through the writings of as many historians from the period you are researching and comparing the story from as many angles possible and see if they corroborate with each other.
I suppose it depends where history comes from, word of mouth history can get a person in a lot of trouble going up against someone who goes along with a book created and then altered to fit with the new way of thinking. and then the lack of history in books now. read books outside of school if you want to learn the real history.
A lot of lies mixed with a little truth from my research. People are more closely related than what is being told. Our true history has been buried under a bunch of bullshit, even as I type, it's being fabricated for political or monetary gain to ensure certain blood lines remain dominate in this world. It's who we are. Just go with and enjoy it.
Now, history is very true. But, evolution has no truth in them and it's all lies. Because, it makes statement of "billions years ago", that can never be mesured by any man. Because, what happened billions years ago, is nothing, but assumption, speculation, and guesses. So wherefore, man will tell you a lie story in order for them to make profit out of you.
Okay then, how do you know the Bible isn't a lie? You have no evidence for the creation story of Genesis; no evidence for a global flood; no evidence for the events of Exodus; no evidence for the events of the Gospels; and if there is a god, you have no evidence that it's Yahweh. Without the Bible, you wouldn't know about anything it has to say.
If the book of Genesis was not true, we shouldn't have existed then? If the flood of Noah didn't exist, then we should see dinosours running around today. If Exodus was not true, then we would not have known 10 commandmenth...... The answer to this question depends greatly on what is meant by "conclusive" proof. Can we reach out and touch God or see Him in the same way that we touch and see people? No. But there are countless ways one can know assuredly that God does exist, that He is real, and He is who He says He is. We will look briefly at three ways of proving His existence using both science and the Bible. . . . . . The Law of Cause and Effect. This law of science states that every cause has its effect and every effect has its cause. This law is the basis of all science. As such, this law bears a relationship to the origin of the heavens and the earth. In fact, scientists agree that the universe has not existed forever, that it had a beginning at some point in time. . . . . . . The theory of relativity, which is almost universally accepted among scientists, has certain implications for this Law of Cause and Effect. One is that the universe, defined as time, space, matter, and physical energy had a beginning, that it is not eternal. And it is through Einstein's equations that scientists can trace the development of the universe back to its very origin, back to what is called the "singularity event" when it actually came into being. Science has proven that the universe really did have a beginning. This means that if the universe had a starting point in history, then it obviously began to exist, and it must have a cause for its existence. . . . . . . Therefore, if the universe needs a cause for its coming into being, then that cause must be beyond the universe—which is time, space, matter, and physical energy. That cause must be something similar to what Christians call "God." Even Richard Dawkins, probably the most prominent proponent for atheism in our time, admitted in a TIME magazine article that "there could be something incredibly grand and incomprehensible and beyond our present understanding." Yes, and that is God!
"If the book of Genesis was not true, we shouldn't have existed then?"
Or that it is just one of the many origin myths that are no more true but just as incorrect. There is always the potential for some other reason.
A story does not need to be true for it to be told.
There is no need for an intelligent agent for an aspect of existence itself "cause and effect" to function. As I've told you before there is always potential for some other reason. The cyclical universe (where after the universe reaches a critical point it retracts and becomes a singularity again only to reach critical mass and expand again), there is also the infinite multiverse where there are an infinite number of universes bubbling into existence where the edges of one universe is pressing against the edges of another.
"there could be something incredibly grand and incomprehensible and beyond our present understanding."
As Dawkins almost always follows with this statement is that if such a being existed it would be nothing like the god portrayed in the bible.
