Current Past and Future

What if the stories of Adam and Eve were true? What if time manipulation was possible? What if space and time could be pinched together? What if... The future was trying to fix the past so the past could fix the future. Were the characters in the stories of Adam and Eve, the Amazons of Greek mythology actually sent from the future. If so, why? Three young people, Adam, Eva and Hanna get pulled into the future. They then get sent back to prehistory. Marshal Samuels gets accidently pulled into the future. He is an anomaly. Unlike all previous extraction by the future, there is no record of his involvement in the extraction and re-insertion program. Marshal becomes central in dealing with the appearance of aliens bent on colonizing the Earth. The aliens have superior technology. This is the aliens first encounter with another intelligent species. They go against their own directive of not causing harm to another intelligence. They underestimate the Earthling capability to resist a superior force. The alien leader Maltar is sure of a victory. Marshal and his two sons devise a plan that defeats Maltar. Marshal then goes forward to the distant future to see what has happened to the human race. Has the human race become more intelligent? Has it expanded into the universe? Is earth still viable?
