The wise men did not come to see Jesus until after he was born. At the time they came to see him he was called a small child.
And yes the bible does not frown on the Zodiac. It is using the stars to somehow predict the future is what is frowned upon.
The book of Enoch was not put into the final bible for good reason. It is not divine. Neither is the gospel of Thomas and the others. They were not left out - they were excluded as they do not fit.
And yes, Mary and Joseph were not paupers. And the word for "manger" can also be simply a crib. To see Jesus in a horse stall, with 3 wise men around him, is a double mind-fuck.
