The most comparable concept today to the Goddess Asherah would be “Mother Nature”. In that sense, she is still warshipped and revered today. I agree that Asherah is in the bible (Old Testament)(Judaism), and had been abandoned by the time of the creation of the New Testament(Christianity). She absolutely is in the Bible, even if this is considered a Pagan Concept today.
“To be honest, ancient Greeks and Romans did not take religion that seriously either. They even made jokes about their gods, and wrote comedies depicting their mortal imperfections.”
—This is a little vague. Please let me clarify. There were stories like Aesop’s Fables and Aristophanes The Frogs and Apulius Golden Ass. A certain amount of levity was added, so as not to interpret these stories as Gospel. These stories had more to do with morality than accuracy. For non-comedic writings… you would get several criticisms or writings about mistakes on almost every time a god was mentioned. Herodotus got so much criticism, that he was called “Father of History, Father of Lies.” Many Greeks did in fact takes there religion very seriously. Socrates was put to death, in large part, for his religious beliefs.
On the imperfections, in many ways, the Greeks practiced Hero Worship, in which these Hero’s and God’s were in fact flawed. As for qualities like Jealousy in Hera, or love in Aphrodite, sometimes these Gods were linked to emotions. And Emotion isn’t always pure. It has good and bad in extremes.
On the Hebrew God, with the story of Soddom and Gommorrah, some people have interpreted the Hebrew god as a vindictive God. As for Magic in the bible, I mean there are certainly miracles, and Jesus walking on Water, a burning bush, a parting red sea, Angels, etc… There is magic all over the bible. In America, Thomas Jefferson, wrote an edition of the bible, where he purged all of the magic. This bible never caught on.
