Impossible Journey

Summary

2025 scientists plan to time-travel to Eden to warn Adam and Eve and thus prevent the fall, putting an end to all evil and disease in the world. But they can only travel 200 years, more or less, at a time.
Having gained the needed financial support from wealthy financier, Mark Lewis, the scientists manage to build the first time machine in which three of them take off on their imposing mission.
They visit six different historical time periods including:
*The California Gold Rush of 1849
*Colonial Philadelphia of 1775
*The Renaissance
*Legendary Camelot
Each historical time period they visit points in some way to the true answer they are seeking. But they ignore the obvious and go on blindly with their mission.
At one point, they are pulled forward unexpectedly to their future where robots serve and are forced to fight in a senseless war (WWIII). Will they escape? And will they ever come to learn the true answer to the problem of sin and evil in the world?
