"Besides, why would space travelers go through all the trouble to make up a "story book" for us humanoids?"
They didn't. We did. Its natural for people to seek explanations for things. When they can't, they make one up. Have you heard of the cargo cults? Google it. Really facsinating.
"Why would they seed the planet, then come back to jack with us."
I guess there I'm operating off the presumption that no matter how "advanced" people get, there still will be competing ideologies and types of people.
"Would you not think an advanced race would dispense with such sophomoric games and get on with business. The way you make it sound is that aliens from outer space are playing a kind of human chess game."
I would "hope" an advanced race would, but I am, after all, a Pessimist. Besides, there is always a considerable distance between the "highest" and "lowest" of a given society or species. Look at mother Theresa vs. the thugs of N.O.
And of course what appears to be "jerking around" to us might actually have had some purpose, etc.. we can't understand.
Anyway, bottom line: I have no proof one way or the other regarding our history. And while I respect your faith, you have to admit at some level that you really have no proof either.
Honestly, take a minute to check out cargo cults. It really is a fascinating little story from the post WW2 era w/ a lot of implications.
