While Smith's main changes simply moved the Promised Land and the Israelites to Utah, Hubbard started from scratch. Brand new deity and humans as a type of damaged god originating from another planet. Though he did copy the idea of salvation through restoration by faith.
If you and I set sail today to start a religion then we have behind us the fact that a huge percentage of the population is already part of a religion. In other words we are offering another version of what is accepted, the latest model
The Bible includes several contradictory claims from different authors and clearly the creation story departs wildly from the geological and biological evidence. I see no plausible basis in truth for Genesis.
I have seen both the list of contradictions and the equally big list of answers from the Bible side.
As to Genesis God could have made the sun as a a star already 5 billion years old and ditto for earth. Adam and Eve were portrayed appearing as adults.
Consider this.....in 1800 an alien detonates a nuclear bomb. To the scientists of the day what happened is impossible. Their calculations show that it would have taken a 1000 men with wagons 10 years to assemble the explosive. To the non scientists it was also impossible, perhaps a miracle.
As would be expected the event would be written about and by both men of science and journalists. However, in both cases their writings would be way off the mark.
Perhaps there are aspects to our existence that lie beyond our current understanding. I too have had experiences that suggest some of those possiblites. However nothing I have experienced suggests anything out of the ordinary about the Bible.
Like you I can't relate my experiences and observations to the Bible except they share in common with the Bible things that just don't add up, something else at work.
It is amazing what a story can become over time. Parting seas or bringing back the dead? I don't thinks so. Feeding a multitude on some rock hard stale bread and two rotten fish perhaps. I can just imagine, "Thanks but I will be OK, pass it on".
While it is true that a story can become a lot over time the story usually has a starting point or a factual basis.
Actually, if I stand on the side that supports the Bible as basically accurate then to my way of thinking it portrays a god of great but limited power. I think it is quite possible that the universe came about without a supernatural being but gods or superior beings are within the universe.
If I go back to the alien who detonated the thermo nuclear in 1800.....no matter the effort put in to find an answer the science of the day could not come within a million miles of the explanation. Every theory or explanation would be full of holes and counter theories. Then one day in the future the answer would become obvious. At the moment I see Hawking, Davies and Co as being the counterpart of those scientists in 1800.
