There are many misconceptions about the bible. All the doubts and questions come from ignorance. Ignorance because more than half of the story was kept from humans.
Remember one thing: The bible was invented but the Roman Empire. Emperor Constantine ordered the confiscation, review and compile of the ancient sacred texts and create a book that would rule the new official religion of the state: Christianity. he concept of monotheism was introduced, everybody was forced to follow christianity without question it or face prosecution by the sword. Constantine became the representative of God on earth.
The bible is composed by the old testament and the new testament. The old testament was taken in part from the Torah, from those ancient texts. But there were many other texts that were left outside for the convenience and control of the Empire. For example, the book of Enoch, where Enoch, one of the patriarchs of humanity, lived with The Gods for 300 years in space. In his book, he even describes how the earth look from space, and how the pyramids in Egypt look from the air. Enoch also goes deep in describing the flying machines of The Gods, something that the Mahabharata also describes in detail in the section called Vaimanika Shakstra (which means science of aerobatics) in the book of Bhagavad Gita, these flying machines were called Vimanas, and the description of their propulsion system is described as antigravity based on sold mercury as superconductor creating a spinning vortex.
The book of Enoch is just one example of a book left outside of the bible for the convenience of the state. (todays DEEP STATE) Enoch also goes in detail about the situation of the fallen angels and the nephillim. The Gods that were in orbit with the duty of patrolling earth, observing humanity, collecting all their data, could not resist the temptation that humans reproduced fast, giving birth to beautiful wild girls that look just like them. After all, these aliens created us in their image, after their likeness. These Gods decided to illegaly come down and grab as many women as they wanted. The raped them, killing many of them because these beings even though look exactly like us, they are bigger physically than us with penises way bigger than us. The women who survived became pregnant from a species not entirely compatible and gave birth to defective creatures who crew up out of control. The Giants, the Nephillim.
The new testament is composed by the books of the apostles describing the life of Jesus who was full blooded God. In an attempt to steer human civilization off evil, A specific God, I wont go into that story now because is long, was artificially inseminated into a human virgin female. As the story tell us, "two angels came down to visit mary and they told her she will become pregnant" She was put into a trance (anesthesia) and was artificially inseminated. When Jesus was grown enough, was approach to start his training towards influencing the civilization. The plan failed, and he was brutally assassinated by humans. Nevertheless, his word was spread enough around the world to make an impact and make a difference. A difference that to this day preserves stability and self control in the society.
